Meng Ming referred to the style of the "Yuan Datou" silver dollar issued by later generations, and designed the pattern of the coin, including thickness, pattern, face value, anti-counterfeiting and other aspects. The coin is round and without holes, and the outer ring is mainly straight-edged; Out of a hundred coins, the rest of the pattern is unified with the obverse is the side portrait of Zhao Zhen, and the top is "the third year of the Great Song Dynasty"; The back patterns are all dragon and phoenix patterns, with the words "Yiwen", "Wuwen", "Yishiwen" and "Ershiwen" in the center, and Arabic numerals are added below; The obverse pattern of one hundred texts is a profile portrait of Liu E. The coin material is a copper alloy.

Then it is up to the gold and stone carver to make the mold, which is usually made of special steel, and its surface is engraved with patterns and has a hard texture. The surface of a coin can be made to have a mirror effect during the minting process. The molds are made by hand, and the engraver uses special tools to painstakingly carve out words, numbers and various patterns on the surface of the mold.

Meng Ming used the stamping coinage method, and earlier Meng Ming and Chen Qinian designed a large stamping machine, which used "crank power" to drive the stamping head up and down (like finger joints bending and straightening) to complete the stamping. It takes hundreds of tons of pressure to make a working die by stamping the original mold, and although the tonnage of the stamped coin is smaller, it also requires considerable pressure, such as the pressure of this copper coin is 22 tons per square centimeter. Ten presses were eventually built, and more had to be added later.

After the process of embossing coins, Meng Ming and Chen Qinian designed a mechanical movement mechanism for synchronous blank cake injection with the stamping machine, which continuously puts the blank cake into the embossing position at a fast speed and the stamping can be completed instantly, so there are more than 100 coins gushing out every minute. One million and forty new coins can be produced in a day

In the early days of hand-hammering, metal washer technology was used, which is still used today, by cutting a round hole in the metal plate with the same diameter as the coin, and placing the blank cake into the hole to prevent the blank from spreading and deforming due to compression during the stamping process. Coins with toothed edges require the inner side of the metal washer to be designed into toothed shapes, and when the machine stamps, the toothed and front and back patterns around the blank cake are embossed at the same time to become a toothed coin; For coins with lettering on the perimeter, the text is embossed on a hydraulic press using a working die with lettering around the perimeter and a metal washer that is divided.

Finally, the polishing and polishing of coins, Meng Mingyou borrowed from the shot blasting machine used in later foundries to build a coin polishing machine. The coins produced in this way are many times more delicate than the coinage of the imperial court, and should not be forged.

Half a month later, the coin stamping project presided over by Meng Ming and Chen Qinian was officially completed, and 300 physics students from the University of Tokyo participated in the development and construction. Meng Ming decided to produce a new batch of coins before Zhao Zhen's Christmas Day, which could issue about 10 million coins.

The production of the printed corner coins of the banknotes is much simpler, and the pattern is designed first, among which the front of the banknote with the amount of 50 yuan and below is the head of Zhao Zhen, and the lower left and upper right corners are the denomination numbers "One Yuan", "Wu Yuan", "One Shi Yuan", "Two Shi Yuan", "Wu Shi Yuan", "Wu Shi Yuan", and "Da Song Coin Bureau" is written above; The back is the real dragon pattern on the right, the left is the scenery, one yuan is the sunset of Leifeng Pagoda of Hangzhou West Lake, Wu Yuan is the Du Fu thatched cottage in Chengdu in spring, one is the autumn scenery of the Great Wall, two Shi Yuan is the scenery of Qiongya, Wu Shi Yuan is the Zichen Hall of the Imperial Palace in Tokyo, and the top of the back is also written with "Great Song Coin Bureau", and the four corners are the denomination numbers; The denominations are one hundred yuan, Wu Bai yuan, and one thousand yuan, the format is the same, but the characters on this side are different, and the front is the portrait of Emperor Zhenzong, Emperor Taizong, and Emperor Taizu.

The most important thing for banknotes is to prevent counterfeiting, and the paper used in Meng Ming's printing banknotes has also been improved, and the paper raw material is short cotton lint, which is made of 95% cotton linter and 5% wood pulp; The paper is strong and has a high folding resistance, which is conducive to prolonging the life of circulation. It can make a crisp sound when shaking, and the banknote will not break when folded, and it will not be broken when you put the banknote in the palm of your hand. From the paper alone, the process cannot be made, and the authenticity of the banknote can be distinguished from the paper. Meng Ming kept the papermaking process strictly confidential.

And add a watermark and color fiber on the paper, the watermark is in the process of banknote printing, through a special banknote pattern mold, change the density of the banknote fiber, in the case of light perspective, the banknote paper will produce a pattern through the change of density, and the watermark pattern is the head of the four emperors of the Song Dynasty.

The pattern coins of coins and banknotes have been produced, and Meng Ming presented these patterns to Zhao Zhen when there were still six days before Zhao Zhen's birthday, and Zhao Zhen was immediately attracted by their exquisiteness, and he called Liu E to watch it, and Liu E's expression was the same as him. Especially when Zhao Zhen and Liu E saw their avatars on the coin, they had a very satisfied expression, which is not exempt from vulgarity, even the emperor and the queen mother have vanity. The two of them praised unanimously, and finally called the ministers of the government hall, the privy envoys, the three envoys, and the chief officials of the six ministries to come and watch, and when they saw this exquisite coin, they were all amazed and praised. But most of the portraits of Liu E on the 100 Wen coins were secretly slanderous, and they looked at Meng Ming with some dissatisfaction. Meng Ming didn't think so, and pretended not to see it.

At this time, Lu Zongdao hurriedly said: "Meng Yuma, is the female portrait on this Baiwen coin the Queen Mother?" Meng Ming said yes, and Lu Zongdao suddenly said angrily: "Meng Yuma, I really misjudged you, so I am ashamed to invite merit and happiness." Meng Ming was also angry and said: "Lu Getai, the lower officials respect you, but please pay attention to your words and deeds, why can't the queen mother's head be engraved on the coin, don't say any clichés about Si Chen and the Empress Wu." “

Meng Ming also quoted two passages from Li Zhen's "Burning Books: Answering the Short View of Women's Learning the Tao": "It is recorded in history that Yi Jiang started with a woman and nine others, and made up the number of ten people, which did not prevent her from being listed as one of the ten "virtuous ministers of the country" of King Wu of Zhou along with the Duke of Zhou, the Duke of Zhao, and the Duke of Tai. Wen's mother is a saint, and the "Zhou Nan" and "Zhao Nan" in the "Book of Songs" are attributed to Yazheng, which does not prevent her from being called the "Four Friends" with San Yisheng, Dayan and others. What they are pursuing is only the worldly law, the deeds of peace for a while, and they do not dare to discriminate against men and women according to their strengths and weaknesses, not to mention learning the truth beyond the world, and want to become like Shakyamuni Buddha and Confucius who seek the truth in the morning and do not hesitate to die at night! If these characters were heard by the people in the alleys, they would reproach and demand that they should be women who do not leave the boudoir and are docile and shallow, as stipulated in the Confucian classics, and treat Wen Mu and Yi Jiang as slave servants. Therefore, those who think they have a vision must not be ridiculed by the truly wise people, and they must not be in a hurry to win the likes of ordinary people. If you want to be liked by ordinary people, then you yourself are just ordinary people. What is this vision? Or is it short-sighted? You should distinguish clearly.

I said that such a far-sighted woman is a good sign of good luck for others, not a hundred years of accumulation, and it is not easy to produce. There was a woman named Xue Tao in the Tang Dynasty, a native of Sichuan. When Yuan Weizhi heard her reputation, he specially asked to go to Sichuan and meet her.

Xue Tao wrote a "Four Friends Praise" to thank him for his kindness. Wei Zhi really admired it very much. Yuan Weizhi was an outstanding poet in the Zhenyuan period, could he easily admire people? Alas! A woman with a literary talent like Xue Tao can still make people admire her thousands of miles away, not to mention practicing Buddhism and traveling in the world, if you meet someone who is beyond the world, is there anyone who is not convinced? There won't be. Haven't you heard the story of Pang Gong? Pang Gong is a native of Hengyang in your Chu land, he and his wife Pang Po and daughter Lingzhao worship Matsu as a teacher, seeking the Buddha Tao that is beyond the world, and they finally turn away one after another, becoming a person who is beyond the world, and it has become a happy thing that has been passed down through the ages. I hope you learn from their vision. If you say, "Wait until I go and consult with the ordinary people", then it is not for me to know. ”

Meng Ming also said: "At the beginning of Confucius's establishment of Confucianism, there was no injustice to women, and he personally edited the Book of Songs, which praises the equal love concept of men and women. The "initiator" is Dong Zhongshu, who proposed that "the monarch is the minister, the father is the son, and the husband is the wife", and his "three guidelines" can regulate the dignity and humility of the monarch and the minister, father and son, and standardize ethics. But in the family, why should women also be involved? This completely turned women into appendages of men, and the originally harmonious relationship between men and women slowly evolved into opposites. In the eyes of the lower officials, women and men are equal, not only can they study, but they can also be officials and politicians. ”

Lu Zongdao was refuted by Meng Ming without saying a word, and he was embarrassed. Kou Zhun came to relieve the siege, and he said to Meng Ming: "Meng Yuma, what you said is also quite reasonable, I know you don't like Dong Zhongshu, but that's your way; Lu Guanzhi also has his own way, but he follows the current ethics. The two of you are just a battle between the new and the old, and no one can say anything about it at the moment. Don't go all the way, just let time test and judge. ”

He said: "Lu Guanzhi is too worried, this coin is a thing in circulation, no one's avatar will affect anything, nor can it affect the country, and the queen mother has worked hard and has high achievements, even if she is famous and qualified, she can be engraved on the coin." ”

In the end, the ministers did not raise any further objections, and unanimously agreed to issue it on the Wanshou Festival, and the government affairs hall made relevant arrangements, and the three envoys proposed that the old system of money should be gradually recovered in the future, and new money would be issued, and that the old system of money could not be used for future taxes, military salaries, and government procurement, and all new money would be used for circulation.
