After the bank opened to the north and south of the country, it temporarily stopped the pace of expansion, because there were not enough people. Zhu Youxiao found that Arabic numerals had been transmitted to China, but they were not widely used, so he announced that all banks used Arabic numerals, instead of the original yards, and took out the simple addition, subtraction, multiplication and division symbols, stipulating that bookkeeping must have both Chinese numerals and Arabic numerals, and the general ledger and sub-ledger must be clear, and the accounts must be cleared every half month, in case someone cheats and embezzles after the increase in banking business in the future.

The mint used hydraulic machinery, so the output was very high, but Zhu Youxiao required that there must be enough silver to deal with the run before it could be implemented everywhere, although the current run did not occur in the north and south of the country, but it is not certain that it will happen in other places, so it is always good to be prepared.

Beginning in December, all military salaries in Liaodong were paid in silver coins, and the bank set up a branch in Shanhaiguan, while branches in other parts of Liaodong had not yet been established. Therefore, it can only be exchanged at Shanhaiguan, but according to the statistics of the Shanhaiguan branch, in a month, there are very few people who come to exchange silver, but some people come to exchange silver for silver coins.

In the first month of the second year of the Apocalypse, the emperor decreed: the copper coins and treasure banknotes of the North and South Zhili can be exchanged for new currency in the bank according to their fineness, and by the third year of the Apocalypse, the use of old copper coins and treasure money in the North and South Zhili will be stopped. By the fourth year of the Apocalypse, the use of old copper coins and treasure banknotes was stopped throughout the country. As for silver, there was no rule that it could not be used, but he believed that the difference in convenience between silver taels and silver coins was too great, and that silver coins should gradually drive silver taels out of the market.

Li Zhizao came to ask for instructions on what to do with the copper coins and treasure banknotes received, and Zhu Youxiao demanded that all the treasure banknotes be destroyed, and the copper coins could be remelted to make copper coins. However, Wei Zhongxian came up with an idea to sell copper coins to other countries, such as Japan.

Japan has never had its own currency, in fact, many countries around the Ming Dynasty used the copper coins of the Ming Dynasty as currency. Of course, Wei Gonggong didn't know, but after Zhang Qianfang started to conduct sea trade, he had been exchanging raw silk and porcelain from the Ming Dynasty for Japanese copper, and it was Wei Zhongxian's subordinates who were responsible for contacting Zhang Qianfang. After Zhu Youxiao ascended the throne and appointed Wei Zhongxian as the governor of Dongchang, Zhang Qianfang's contact person became Dongchang. Because Zhu Youxiao attaches great importance to maritime affairs, Wei Zhongxian is also very concerned about Zhang Qianfang's situation, a few days ago Zhang Qianfang's contact person occasionally said a sentence: "It is actually more cost-effective to buy copper with copper coins, almost five times the profit, but unfortunately there are not so many copper coins." But let Wei Gonggong keep it in his heart, now that so many copper coins have been recovered, wouldn't it be more cost-effective to ship them directly to Japan?

As a modern person, Zhu Youxiao certainly understood the benefits of controlling a country's currency, and when he heard that there was such a good thing, he immediately instructed that all the recovered copper coins be transported to Quanzhou and handed over to Zhang Qianfang to be transported to Japan for copper. He also asked Dongchang to set up an office in Quanzhou to cooperate with Zhang Qianfang to deal with the shipping of copper coins.

In October of the 47th year of Wanli, Zhang Qianfang took his subordinates and drove a half-new ship from Tianjin, and finally returned to his hometown Quanzhou. Because it was the first time to sail on the sea for a long time, everyone arrived in Quanzhou, and after going ashore, they were all unstable on their feet.

Zhang Qianfang had been on a sea ship before, so he behaved a little stronger. He took his subordinates to find the contacts in Quanzhou first, and after arranging their residences, he explained to his deputy Shen Congjing and walked to his house.

The closer he got to his home, the more excited he became, and as soon as he walked to the door, his family member Zhang Liangcai jumped out, hugged him and shouted: "It's Young Master Qianfang, God, the little young master is back." Then he looked at him carefully and said, "The little young master has suffered outside, and he has lost a lot of weight, and the old lady is going to be heartbroken." “

Zhang Liangcai is an old family member in the family, and it can be said that he watched the two of them grow up, Zhang Qianfang also said excitedly: "Uncle is still the same, Qianfang is outside, I have been thinking about Uncle and Xiaojie, what about Xiaojie, are you still following the shopkeeper Wang?" “

Zhang Liangcai's face changed and said, "Don't talk about him yet, let's go see the old lady and the young lady." After that, he pulled Zhang Qianfang and walked inside, shouting, "Old lady, the little young master is back." “

Zhang Qianfang entered his parents' room, and his mother Yang was sitting in the chair in the middle, holding a little girl of three or four years old, and a delicate woman was standing behind. Zhang Qianfang knelt on the ground and began to kowtow, shouting in his mouth: "The unfilial son Qianfang has seen his mother, I wish my mother good health." “

Yang looked at the son in front of him, tears flowed out involuntarily, hugged the girl on his body, pushed her and said, "Quick, call you Abba, poor child, I haven't seen Abba for two years." “

The little girl twisted her body and didn't dare to step forward, Zhang Qianfang wiped her tears, stretched out her hand and said to her daughter: "Nannan, I'm Abba, come and let Abba hug you." “

The little girl hesitated, and then the beautiful woman behind her gently pushed her from the side, and the little girl finally stepped forward and let Zhang Qianfang hold her in her arms.

At lunchtime, the little girl Zhang Ting finally got acquainted with her father, so she kept distributing vegetables to her father during the meal, saying: "Abba didn't eat outside, he was so thin." It made everyone laugh.

In the afternoon, after Zhang Qianfang's father and brother Zhang Qianshu came back, the three of them came to the study together. Zhang Siyou said: "Why are you back? “

Zhang Qianfang replied: "Tell my father, the child was originally in the Beijing camp and had no chance to rise, and at this time, the imperial grandson wanted to learn martial arts, so the child was selected to accompany the imperial grandson to practice martial arts. The imperial grandson was quite interested in shipping, so he sent his children to Quanzhou to open up the sea route. “

Before Zhang Siyou could speak, Zhang Qianshu spoke: "Father, the emperor is in good health today, the prince is in his prime, and this emperor is ...... grandson."

Zhang Siyou thought for a moment and asked, "The imperial grandson is so young that he is interested in shipping?" “

Zhang Qianfang said: "The child has been with the grandson for a long time, although the grandson is not very old, but he has excellent knowledge and treats people with sincerity. “

Zhang Si nodded and said: "Since you have identified the Taisun, then you must always be loyal to the Taisun, no matter what happens in the end, you must not have other ideas, do you understand?" “

Zhang Qianfang said: "My father often teaches my children to be loyal, and my children will not live up to my father's teachings." “

Zhang Siyou said with a smile: "Well said, since you are presiding over the shipping for His Royal Highness the Grand Sun, then when I go to see your uncle tomorrow, you can talk to him." “

Zhang Qianfang was able to be alone with his wife Liu Li at night, Liu Li touched his thin face, and said lovingly: "Everyone is thin like this, no wonder you don't recognize you." “

Zhang Qianfang held his wife's hand and said: "I have taken pity on you in the past two years, it will be fine in the future, I should be stationed in Quanzhou, if I really want to go back to Beijing, I must bring you and Nannan to Beijing, and I can rest assured that I have my brother and sister-in-law to take care of me at home." “
