The blade in "Three Knives" is a traditional product of Haining. "Zhou Shunxing" improved the forging and casting process on the basis of local kitchen knives, and made a thin, uniform, sharp and cheap leaf knife, which achieved the purpose of cutting leaves like hair and feeding young silkworms, and was well received by silkworm farmers. However, it is said that during the Guangxu period of the Qing Dynasty, Empress Dowager Cixi heard that Haining had the name of "Ye Dao" and thought it was taboo with her own name "Ye Na La Shi", so she changed her name to "Sang Dao".

However, this "mulberry knife" has the same name as that used by Haining people to graft mulberry seedlings, which is not refreshing, so we have to add a verb in front of each other, that is, "mulberry knife" and "mulberry knife", but it is still very awkward. You know, once folk customs have formed their own unwritten laws and regulations, it is difficult for people's subjective will to change. So when Cixi died, "Ye Dao" and "Sang Dao" corrected their real names.

According to historical records, Zhou Futing, the founder of his medicine knife, was adopted by the female shopkeeper of "Zhou Shunxing Tiedian" when he was young. His original surname was Cao. /kloc-When he was 0/3 years old, Zhou Futing went to Zhuji to learn the craft of green knife furnace. After studying for four years, he returned to the store. When Zhou saw that there was a shortage of medicine knives in the market at that time and the price was high, he went to Hangzhou Hushu Medicine Knife Workshop to observe and steal the skills. After sample imitation, research and improvement, a high-quality top-grade medicine knife was finally made.

It was named "Palm Brand" because its blade was made of old German file steel "Palm Brand". In addition, when forging and casting, Huainan lump coal is used to quench and grind, and Zhenjiang Dantu's famous "children swinging bricks" is used to sharpen the knife, so that the medicine knife is of high quality and quickly enters the market. At that time, Nanjing, Beijing and even Yunnan, Guizhou, Xinjiang, Heilongjiang and other places came here one after another. Well-known pharmacies such as Hu Qingyutang in Hangzhou and Tong Ren Tang in Beijing all designated them as special products, and their business is booming.
