It is sad to ask for it, to give it up, to give it up without hesitation. According to Anya's meaning, no matter which possibility it is, Sima Cheng is destined to be a poor person.

"The one who bows, kneading the wood and the string is the arrow". The most important process of making a bow is to bend it.

The number of shipbuilders is very large, when the Eastern Jin Dynasty Emperor An, Jiankang was a typhoon, and the official and commercial ships destroyed amounted to about 10,000. In Hebei, Ding, and Xiangzhou, the number of shipbuilders reached 3,000.

How to increase the speed of the ship is an important issue in the design and construction of ships. The new type of warship designed by Li Gao "carried the second wheel, sailed in the wind and waves, and was as fast as a sail seat".

Due to the needs of war, the strategy and tactics of attacking cities and conquering places, as well as the manufacture of offensive and defensive equipment and weapons, have developed to varying degrees. In terms of offensive and defensive equipment.

Shipbuilding technology also developed greatly during this period. Soon after the establishment of the Sun Wu regime, it had more than 5,000 ships and ships, and constantly sent a relatively large fleet to Liaodong in the north and the South China Sea in the south. Among them, the large ship has five floors and can carry 3,000 people.

Liang Houjing is particularly prominent in the production of siege equipment, once "set up a hundred-foot building car", and also built flying buildings, crashes, climbing cars, hook wood, step cars, trains, etc., "and several zhang high, one car to twenty wheels". Offensive and defensive equipment played a large role in the war.

The crossbow machine tends to be large-scale, "the big crossbow of China and North Korea, with 20 crossbows,.. Liu Yu attacked Lu Xun, and there were more than 10,000 crossbows in the army, and everything was destroyed."

In preparation for the destruction of Wu, he invented the shipbuilding method of assembling many small boats into one large ship. This kind of large ship is called "Lianfang", "one hundred and twenty paces square, and two thousand people." Take wood as the city, get up the building, open four out, and have to gallop back and forth on it"

The number of shipbuilders is very large, when the Eastern Jin Dynasty Emperor An, Jiankang was a typhoon, and the official and commercial ships destroyed amounted to about 10,000. In Hebei, Ding, and Xiangzhou, the number of shipbuilders reached 3,000.

Danyang has a fighting field brocade department, which is undoubtedly a government textile handicraft industry. This kind of weaving mechanic is Liu Yu after Yao Qin from the "Pingguan right move its hundred workers". Subsequently, the brocade department became a permanent textile institution of the handicraft industry of the Southern Dynasty government, making royal clothing.

The longbow has a simple rounded arc shape, and there is no complex shape of the Celestial Empire Angular Bow that curves back. If you don't need to roast the bow, it will reduce the tension of the bow, and you won't be able to bend it all at once, so that the back of the bow will not break and cause internal injuries and lose its elasticity.

The process of bending is called "taming the bow", which is to allow the bow back to gradually adapt to the bending. To do this, you need a special bracket. The bracket can be made of hardwood, with a groove dug vertically at one end to support the bow, and the other end managed to be fixed vertically to the ground.

Tie the rope to both ends in the relaxed state of the bow back, put the center of the bow back on the groove of the bracket, use even force, slowly pull the string, and hang it into the first string groove, and the bow back is slightly bent.

At this time, it is necessary to carefully check whether the curve of the bow is smooth and even, mark the areas that are too stiff, relax the bow back and trim and fine-tune until you are satisfied.

Then pull the rope apart, gradually increase the opening and hang the groove downward, and keep trimming the bow back until a satisfactory and uniform arc is formed.

It is precisely because Sima Cheng rarely goes out to show his head that the rumors about him in Luojing City will intensify.

Every time he gets closer to the "truth", Sima Yun's heartbreak is a little more.

Every three or four chord grooves are added, and the rope can be tightened. This process should not be rushed, especially before each increase in the opening, it is best to let the arch back "rest" so that the internal stresses can be relieved to avoid damage to the wood.

Don't tighten too much each time, it's best to tighten one inch at a time. When the full bow opening that is suitable for the archer is reached, the bow is tamed.

Refers to the maximum opening that the archer can pull out, which is equivalent to the distance from the palm to the chest when the arm is stretched out. At this time, remove the bracket and brush the arch back with several layers of linseed oil as a moisture protection layer.

When the oil is dry, you can hang the strings. The bowstring is made of sheep intestines or tendon tanning, and the elasticity and toughness are very good. The fixed opening when hanging the string is controlled by the distance between the bowstring and the center of the bow back to reach the height of the fist.

Great importance is attached to the development of the textile industry. Establish officials, have a fixed official office, and manage them by special personnel.

"Zhongshangfang and don't lead the other bureaus, Jingzhou Silk Bureau, Yongzhou Silk Bureau, Dingzhou Silk Bureau four bureaus", "Si Dyeing and don't lead Jingfang, Hedong, Xindu three bureaus".

War is frequent, but the government-run iron smelting industry in the middle reaches of the Yellow River can still maintain production. The area south of the Yangtze River suffered less damage, and there were still more iron-smelting workshops that continued to develop, while copper, silver, and gold mines were in decline and decaying.

At that time, the center of the silk weaving industry was still in the north, and until much later, Dingzhou was still the place where the most tribute and silk brocade were made. The fabric is very fine.

In the biography, it was recorded that Yuanzhong "once paid tribute to Shizong with a plate of peach wine, and Shizong reported it with a hundred practices", and some recorded that Zu Ting "went out of Shandong Dawen Aya and connected more than 100 horses such as Peacock Luo, so that the concubines threw the pu and gambled on it, thinking it was fun".

Eighteen kinds of martial arts are passed on by word of mouth, and they practice technical skills. Comforting myself as I walked, how could there be such a coincidence...... Nor is he alone......

At other times, there are also weaving bureau Lingcheng, weaving doctors, small weaving sergeants, as well as sewing workers, carvers, Wei workers, glass workers, wedge workers, performance workers, silk weaving, weaving, weaving groups, etc.

There is a saying in cotton cloth: "Fujian people take cotton as Jibei", and some people began to grow cotton a long time ago.

"Fu Zhen was born of play, all of them are China and the Western Regions, and other things are not as good as them, the yellow cloth of Daijun is fine, the Lelang practice is fine, and the Taimo cloth of Jiangdong is white, so it is not as good as the cloth woven by the white stack is fresh and clean."

The cloth woven by the white stack is the "white stacked cloth" produced in the Western Regions. At that time, the cotton cloth woven by ethnic minorities in the northwest region had been introduced to the Central Plains.

Later, cotton cloth was widely popular. Gaochang is a cotton-producing area, and in the ancient tombs of Hara and Zhuo, a kind of brocade with four colors of red, pink, yellow and white composed of geometric patterns has been unearthed, which is a mixture of silk and cotton.

In the tombs of this period, white cloth made of pure cotton fibers was also unearthed, and it was also found that in the first year of peace, there was a contract to borrow cotton cloth and brocade. Sixty pieces of cloth were borrowed at a time, and the cotton cloth was apparently produced locally.

Cotton cloth and brocade cloth are used as a means of circulation, which shows that the production of cotton cloth will not be very small.

It has been recorded in the biography that Gaochang "its land is high and dry", "the cold and summer are similar to Yizhou, and the nine grains are planted", "there are many plants and trees, there are grass such as cocoons, and the silk in the cocoon is as thin as this, and the name is 'white stacks', and the people of the country take and weave it as cloth. The cloth is very soft and white, and it is used in the market". In addition to Turpan, there are also cotton fabrics in the Yutian area.

After the party, Lu Ji's younger brother Lu Yun, an optimistic young man who loves to laugh, advised his brother not to be so impulsive:

"People are northerners, and it's normal that they haven't heard of our Wu County celebrities."

Lu Ji replied with a very famous sentence:

"My father and ancestor are famous in the sea, and I would rather not know, the devil dares!"

It is true that Lu Xun and Lu Kang are famous at home, but what is Lu Zhi a "devil"? Later, Lu Ji made a mistake under Sima Ying, the king of Chengdu, and Lu Zhijin's slander caused Lu Yun and others to die.

In the future, the country may really change hands.
