Nagata Tetsuyama, chief of staff of the Japanese Taiwan Army, handed over the signed text to Xu Yuanjin, and then Liu Deyi announced that he would accept the courtesy and asked the Japanese representative to withdraw. There was thunderous applause. Kenjiro Tian and the others saluted Xu Yuanjin again, and then left the hall quickly.

The reception ceremony lasted only 5 minutes in total, but it ended Japan's 28-year occupation of Taiwan, and the treasure island of Taiwan returned to the embrace of the motherland. In order to permanently commemorate Taiwan's return to the embrace of the motherland from the rule of the Japanese invaders, the Chinese government has decided to commemorate March 25 as the "Taiwan Liberation Day".

After the Japanese Government announced that it would return Taiwan to China, it ordered the Japanese troops in Taiwan to make atlases of the land, houses, and materials owned by the public, whether military or non-military, indicating the location, variety, and quantity, and hand them over to the Chinese for acceptance. The Chinese Government appointed Xu Yuanjin as acting chief executive of Taiwan to take charge of the success, and because Xu Yuanjin had done a great deal of preparatory work in advance at Yang Shuoming's request, and there were responsible personnel for the civilian, financial, construction, educational, military, and police departments, the work of receiving the work was very smooth, and the naval base's equipment, materials, and ancillary equipment, which Yang Shuoming attached the most importance to, were received by commissioners sent by the Navy Department.

In a letter to Ba Yuzao, chief designer of the "Xiangyu" aircraft factory under the "Renhe Group," Shi Xuanhou, president of the Mawei Shipyard, recorded some details about Taiwan's takeover.

"The Japanese army's naval machinery facilities in Taiwan include the Keelung Shipyard in the north of Taiwan Island, the Zuoying Shipyard in the south, as well as the Aircraft Department, the Airfield, and the Civil Engineering Department. The former had been received by the Admiralty, and the latter had a floating dock in the shipyard, which had been towed back to Japan by the Japanese before the war. Most of the warehouses and buildings are located in dozens of locations near Keelung, Taipei and Kaohsiung, Tainan. The stored materials are accumulated over more than 20 years, and there are a lot of them. The mechanical premises alone consist of three departments: the Facilities Division, which manages the harbour, the fort and all civil works; The work department manages the repair and manufacturing of naval vessels; The Rescue Department, which manages the salvage of sunken ships. Although I was a little late, the reception work was quite smooth, and after I sent personnel to investigate, only the salvage company was a private enterprise, which appeared and disappeared and could not be investigated, and this situation was quite common at that time, needless to say. ”

"There are three things worth mentioning. First, the Japanese army had already prepared an atlas for our country to send personnel to receive it. Before our side received the book, the Japanese army was still responsible for taking care of it. Once we receive it, we are responsible for it. However, the Machinery Division has heavy responsibilities and a shortage of manpower, so I have not been able to request additional manpower. I am always worried that after receiving it, the materials will be lost, and I will not be able to account for them in the future, and I will not be able to get through it with my conscience, and I will also be criminally responsible. Therefore, the relevant personnel should be particularly careful when accepting, and the degree of intact and defective should be noted in detail, and the person who should be selected for the custody should be responsible for it, and if there is any loss or damage, the custodian should be responsible for compensation. At that time, each warehouse was full of utensils, many of which amounted to hundreds of kinds, and each of which amounted to hundreds. In addition to being amazed, at first I thought that this was a trick by the Japanese army, and they had discovered that our receiving personnel in various places were corrupt and deliberately short-reported and corrupted our receiving personnel, or at least showed favor to our receiving personnel. There is no name for bribery, but for bribery. But this is not the case, and I asked Colonel Wen Yongqingkang, head of the Japanese Work Department. Wen Yongqingkang said: "It is true that the surplus of existing materials is more than the bottom book, but the Japanese side has absolutely no reason to make a short report. In the past, the Japanese government ordered materials from various manufacturers, and manufacturers in order to prevent damage caused by collision and dumping during loading, unloading, transportation, and transportation. Japan has ruled Taiwan for nearly 30 years, and there are many such surplus artifacts. This time, the handover was hasty, and it could only be fabricated according to the original book, and there was no time to count, and the overflow of materials was inevitable. Although he explained the reason for the surplus, I immediately felt that even if the quantity was consistent with the original handover register, the recipient had already received 10%~20% of the surplus. In order to put an end to the evils, I asked him to make a detailed inventory, make up the handover list, and some warehouses were made up two or three times, although the procedures were troublesome, and the real situation of the property must always be clear. Second, every grass and tree in Taiwan is the wealth of our country, and we have the responsibility to manage and protect it, whether it is public property, private property, war property, or civilian property. Although Taiwan did not have much fighting in this war of resistance, it was also bombed and burned by artillery and aircraft. Since the Japanese army withdrew to the mainland, the local Japanese people knew that the overall situation was lost, and they lost their sense of responsibility for management and protection. Some of the raw materials are not used in time, and they are abandoned on the side of the road next to the house, let the wind and rain destroy, the plaster splashes, and the heavenly things are destroyed, which is overwhelmingly emotional. One day, when I walked through the Zuoying Mountains, I saw more than a dozen large searchlights, each more than 10 feet high, discarded all over the ground. Since these searchlights are used for night operations at the dock and are valuable equipment, I asked Wen Yongqingkang about it. Wen Yongqingkang pleaded and said: "This is because Huaji came here to attack, and when it was demolished in a hurry, it was impossible to choose, so it was stored in the grass in the forest to avoid being bombed, and it was too late to settle properly." After Japan prepares for the handover, there are many more urgent things waiting to be done, and naturally it can't take care of these searchlights, and it is really inevitable to take care of one thing and lose the other. I said, 'Now I command you to gather together on the same day, and move in a place where you choose, so that you will not be damaged.' Sure enough, when I went back the next day, I had already set up a temporary warehouse with a rain cover and all the searchlights in place. This is just one example of one department I supervise, and there are many similar examples in other departments. If we don't take it seriously, the Japanese will have to get by, and in addition to being swallowed up by corrupt officials, the amount of losses they have suffered due to the lack of custody and protection is also terrifying. Naturally, I asked the Japanese officials in charge to take responsibility for compensation. However, the Japanese supervisor said that the security bureau forcibly took the short part, although he left a note, but the person who handled it refused to sign and seal the responsibility, and at that time you will receive it in the future, we cannot disobey it, and we cannot bear this responsibility. When I heard the news, I was furious, they used their power to loot without authorization, and refused to issue official procedures, and this matter was spread, and under the testimony of the Japanese, the Security Bureau could not escape its responsibility, but the face of the country was also disgraced. But I can't be appeased by default, because the actual income does not match the bottom book. I visited the Security Bureau to recover the electrical materials from them. After several visits, the director of security always avoided the situation, and formally pursued the case, but never replied. I then telegraphed directly to General Cheng Biguang, who was furious and ordered the police department to send officers to hold me accountable, and Major Xiao Wen of the Navy led the officers and officers of the Navy to accompany me to arrest the Secretary of Security and his subordinates, and to recover all the stolen electrical materials. This incident was later reported by the newspaper, and Yu was greatly deterred by the lawless people who were greedy for ink, and there were few such incidents later. ”,

"This is an official robbery related to me, and let's talk about the looting of Japanese private property by the military and police. When ordinary Japanese in Taiwan are repatriated, they are allowed to bring their own private belongings. However, the Japanese people have been riding on the heads of the Taiwan people for 50 years, and no matter whether they are working, business, medical, or teaching, they are all paid high salaries and rich pockets, and they are hated by the Taiwan people. The Japanese side protested, and General Xu Yuanjin ordered a ban on looting the Japanese people. Some people objected and said to General Xu, 'These Japanese are carrying all Taiwanese anointment, and they don't deserve sympathy at all.' General Xu replied: "Having said that, we should not cheapen those military and police personnel who take advantage of the situation to extort and seize the opportunity to seize and loot on the spot, these property are the crystallization of the Taiwan compatriots' cattle and horses, blood and sweat for decades, and the Taiwan compatriots have never gained any advantage, but it is a great harm to the country's reputation. I think General Xu handled it very well. Later, some lawbreakers deliberately violated the order and were executed by General Xu in accordance with the law, and this trend stopped. Britain and the United States heard about it and praised it. The Japanese people are inexplicably grateful, and the Japanese government has also praised it. ”

"Because of Wen Yongqingkang's deferential appearance, I talk a lot. In order to test the situation of Japanese ships and planes after the defeat in the war, I asked Wen Yongqingkang: "After the Meiji Restoration, Japan did its best to build a strong army on land and sea. Wen Yongnai replied: "Since your country blockaded the coasts of Japan and Korea, Japan has not been able to support Taiwan, and most of the main ships before the war have been transferred back to China. Most of the garrisons stationed in Taiwan are old warships, which have been slightly repaired and supplemented, and in a short period of time, the troops have been expanded, artillery has been added, and new shooting weapons have been strengthened. Therefore, after entering the war, after a period of main encounters between the two sides, because the sailing speed and artillery range of your navy and air force far exceeded that of the Japanese army, your warships were able to kill the Japanese ships, but the Japanese ships could not hit the vital points of your ships. Since the defeat in the naval battle, the Japanese Navy and Army in Taiwan have lost all their courage, and they are panicked and at a loss as soon as they encounter your army. When the ships were pursued, some were sunk, some panicked, and the remaining ones approached the shallows and sank on their own, so as to save the temporary danger and prepare for future salvage. As a matter of fact, although the Taiwan Strait has held each other for a long time, the number of successes and failures has already been foreshadowed at the beginning of the war. When he spoke, his face was full of sorrow, and he wept suddenly. I asked him to propose a shipwreck site close to Taiwan and make a detailed plan to present, and he agreed and provided a detailed name and tonnage of the shipwreck. ”

Ba Yuzao closed the letter in his hand and turned his head to look out the window, at this time it was late, the stars were twinkling in the night sky, and the factory area in the distance was also lit up, reflecting the stars in the sky.

Ba Yuzao looked at the Mawei shipyard in the distance, and his heart was full of relief and happiness.

Today's Mawei Shipyard, under the auspices of Shi Xuanhou, has regained its vitality and vitality in the shortest possible time, and has not only become an important shipbuilding base in China, but also one of the giants of China's aircraft industry.

Not far from the Mawei shipyard is the location of the "Xiangyu" aircraft factory.

Taking advantage of the opportunity of the First World War, Yang Shuoming, as the supreme leader of the "Renhe Group", established the "Xiangyu" aircraft factory under the banner of "Renhe" in 1917, and Ba Yuzao became the chief designer of this aircraft factory.

The current Ba Yuzao can be said to cherish the opportunity Yang Shuoming gave him to let go of his hands and feet to show his ambitions.

Although it was late at night, Ba Yuzao was not sleepy at all, and his mind was full of the shadow of the new monoplane.

Ba Yuzao opened the drawer and took out the drawings and data that Yang Shuoming gave him as a reference, and couldn't help but be shocked by the whimsy in Yang Shuoming's mind again.

And now, Yang Shuoming's idea of a "monoplane fighter" is about to become a reality.

During the First World War, "Xiangyu" accumulated a lot of experience in manufacturing fighter jets, seaplanes and large bombers, and in a very short period of time determined the hegemony of China's aircraft manufacturing industry. In 1919, Xiangyu received a large order for aircraft: to build 400 fighters for the Chinese Army Air Force. The "Xiangyu" made a number of improvements on the basis of the original design of the original "Blue Bird" series of reconnaissance fighters of Renhe and the company, and as a result, the "Qingluan" type fighter was made. The aircraft redesigned the tail wing surface, modified the radiator and the steel tube welded fuselage structure (replacing the original wooden structure). It is worth noting that the "Xiangyu" company is gradually on the right track by virtue of the good reputation of "Qingluan". The next fighter scheme of the "Xiangyu" is the "Qingfeng-1", which is planned to use a steel tube skeleton fuselage with wooden wings, equipped with a 435 hp (about 320 kilowatts) "Renhe" liquid-cooled engine. The purpose of developing this type of aircraft is still to compete with foreign companies for China's market share, and because of the high expectations for this aircraft, "Xiangyu" even financed the manufacture of prototypes on its own. ,

In 1920, the Chinese Army signed an agreement with "Xiangyu" to produce 300 "Qingfeng-1" fighters, and the Chinese Navy also created a precedent for mass-produced "Qingfeng-1" fighters with the purchase of 12 Yu, and the "Qingfeng-12" fighter that appeared in 1921 was its pinnacle in the field of biplane research and development. In the following time, "Qingfeng-12" and improved models have successively received orders from the Chinese side.

Although the "Qingfeng" series of fighters designed by Ba Yuzao has achieved quite excellent results, what he did not expect was that Yang Shuoming foresaw the end of the era of biplanes ahead of him. At the request of Yang Shuoming, starting in 1921, the "Xiangyu" company carried out a feasibility study on the monoplane fighter, and in August 1921, "Xiangyu" publicly displayed three prototypes of the monoplane fighter it manufactured at home and abroad. The first two (manufactured at the company's own risk) were the "Qingfeng-12" with the lower wing removed and only the upper wing retained. One of the prototypes was also shown in the United States, and the other (equipped with a tail hook) was sent to the Navy for testing. Although test flight results showed that both were faster and more agile than the biplane fighters, they were not satisfactory in terms of maneuvering and climbing, and neither aircraft was ultimately selected by the military. Soon after, the third prototype of the Xiangyu appeared to the world, and its design was inspired by Ba Yuzao's assistant Mao Lei, and its design was full of the times: it used a shoulder-mounted upper wing and aluminum monocoque fuselage, and used a 600 hp (about 441 kilowatts) water-cooled engine to reach a top speed of 213 miles (about 343 kilometers), which was much faster than the first two prototypes with old traditional wings. Unfortunately, the cockpit was arranged behind the wing pillars, which greatly hindered the pilot's visibility. In addition, the prototype's shortcomings in maneuverability were also a real headache, and in the end, the Chinese Army Air Force made the decision to purchase the original "Qingfeng-12" biplane fighter after several trade-offs.

Another prototype designed by Ba Yuzao, the "Qingfeng-122" monoplane postal aircraft, was even more eye-catching. The aircraft was originally designed as a high-speed postal aircraft, and its success was due to the experience gained by "Xiangyu" in the field of civil aviation ("Xiangyu" Airlines, which was founded by Yang Shuoming at the same time, was the predecessor of the later "Huaxia Federal Airlines"). The Qingfeng-122 adopts an advanced cantilever lower wing layout, with an all-aluminum monocoque fuselage and retractable landing gear, with a full wingspan of 18 meters, and can carry 1,100 kg of payload (mail or passengers) to fly about 920 kilometers. The aerodynamic design of the Qingfeng-122 is quite good, but the top speed is only 254 kilometers per hour, and the problem is that the engine power (about 386 kilowatts) is low. Although the performance of the "Qingfeng-122" has many defects, the "Xiangyu" company then developed a twin-engine fast bomber "Snow Goose" for the Chinese Army Aviation on the basis of the "Qingfeng-122", with a maximum speed of 288 kilometers per hour.

In the same year, the designers of the "Xiangyu" company, under the leadership of Ba Yuzao, began the development of a new fighter codenamed "Qian", which was renamed "Qianyi" in December of the same year. This is an all-metal underwing fighter with an aluminum monocoque fuselage similar to the shrunken "Qingfeng-122". The prototype made its first successful flight on February 10, 1922.

It is worth noting that, in addition to the cost of engines and instruments, most of the expenses for the manufacture of the 3 prototypes of the program were financed by the company "Xiangyu" itself. This seems inconceivable to the outside world, because "Xiangyu" is a private company after all, and its sole purpose of investing is to make a profit, not to create an avant-garde test product that no one cares about.
