Which historical figure does Ren Huang always refer to in the TV series Liberation?

Ren Huang always refers to Huang Yanpei, a patriot and democratic educator in modern China. His real name is Chu Nan, and his pen name is Ren Zhi, and his pen name is Bao Yi. He is from Chuansha County, Jiangsu Province.

After the founding of New China, Huang Yanpei broke the rule of "not being an official" and went into politics happily. He has served as a member of the Central People's Government, Vice Premier the State Council and Minister of Light Industry, Vice Chairman of the National People's Congress, Vice Chairman Chinese People's Political Consultative Conference and Chairman of the Central Committee of China Democratic National Construction Association.

Extended data:

Mao Zedong's ci beautifies it, while Huang Yanpei's ci lets it go. The voice is almost the same, except for one word. Therefore, when they communicate by pen and paper, Huang calls Mao "Chairman Run" or "Chairman Mao", while Mao calls Huang "Mr. Ren Zhi", "Ren Lao" or "Huang Lao" or "Vice Premier Huang".

It should be said that even in the era when "class struggle" was in full swing, Mao and Huang treated each other with courtesy, and their friendship for many years was not interrupted by some political differences, which was also commendable at that time.
