How is the secret recipe of Liushen Pill kept secret? Don't let Japanese and Korean elements steal the secret recipe of our ancestors!

Lei Shangyunzi has many traditional secret recipes, the most famous of which is Liushen Pill. Its unique ingredients and secret recipe have been carefully preserved by Lei's family for more than 80 cars. Dedicated to the country after liberation. It is a model of trade secret protection. Lei, the founder of Lei drugstore, has five grandchildren, named "Li Dafang, Geng Erfang, Qi Sanfang, Jiao Sifang and Song". Lei Yuchun, the mastermind of the secret recipe of Liushen Pill, is from the Qi Dynasty to avoid family disputes. 1903, the main members of the Lei family * * signed a collegial agreement. It was agreed to return Liushen Pills to Lei Guang Shangshaofentang for unified sales, but it was confirmed that the patent rights were exclusively owned by Qi Sanfang, which was passed down from generation to generation by the eldest grandson of Qi Sanfang, and they enjoyed the profit commission of Liushen Pills according to the agreed proportion. This agreement effectively avoided the secret recipe leakage caused by family conflicts. The main secret recipe of Liushen Pill is in the hands of Lei's descendants, and its production process is decomposed according to the steps of purchasing, processing and matching. Pharmaceutical workers are not allowed to ask each other: after each post completes the original medicine, it will be collected into the hands of future generations, who will complete the final synthesis in a closed room. At the same time, Leiwan is very strict with employees, and it is forbidden to go out at night to wander, gamble and inquire about business secrets. Offenders will be expelled from the store. Another reason is that employees are paid more than twice as much as other pharmacies, and employees cherish this golden rice bowl very much. Many of them inherited their father's business and worked for Lei for generations. 1937, Japanese invaders invaded China. Leiyuntu pharmacies in Jiangsu and Shanghai suffered huge losses. Japanese invaders covet the secret recipe of Liushen Pill and often come to the door to harass and blackmail. Lei Zhengming, then the manager, avoided the Shanghai Concession in time for eight years. Under the pretext of the boss's disappearance, the employees in the store cleverly kept the secret recipe of Liushen Pill: in the early days of liberation, Lei Shanjue, the heir of the secret recipe, divorced his wife Xu Zhaogu, and each of them kept a secret recipe of Liushen Pill. After consulting with Lei Bifen, party member's eldest daughter who was studying in Tsinghua University at that time, Xu Zhaogu donated the secret recipe of Liushen Pill to the country.
