Is there really a person like Yu Zecheng lurking in history? Please be specific

There is no such person as Yu Zecheng. He is a mixture of many Chinese lurkers.

According to rumors on the Internet:

The TV series "Latent" has become popular, and there have been many opinions on who the prototype of Yu Zecheng is. "Li Qiang is the real-life version of Yu Zecheng." said Li Hua, editor-in-chief of "Red Rock Files Decryption". In "Red Rock Files Decrypted", the legendary story of Li Qiang (formerly known as Li Biguang), an agent who has been lurking in the "Central Reunion" for 10 years, is made public for the first time.

Recently, Li Qiang’s daughter, Ms. Li, showed reporters the 85th volume of "Biography of Figures in the History of the Communist Party of China". The book contains 50 pages of detailed records of Li Qiang’s history. Many details are related to "Latent" matches.

In the TV series, Yu Zecheng was asked by the webmaster to bring his wife to Tianjin, and the organization sent his "wife"—Cuiping, a member of the Communist Party of China. Yu Zecheng and Cuiping also developed feelings at work. In the real version, after lying dormant for several years, Li Qiang became the spy leader of the "Provincial Special Council". The organization hoped that he would get married as soon as possible to facilitate covert work. At first, the organization arranged for a female underground party member to marry him, but Li Qiang disagreed. He believed that two Communist Party members were too dangerous and easily exposed.

In 1946, he married the daughter of the then Secretary-General of the Chengdu County Party Headquarters of the Kuomintang, making full preparations for going deep into hiding. His wife, Zhao Shufang, was simple and kind-hearted. She did not find out that her husband was a Communist Party member until after the founding of New China.
