Who is the prototype of Zheng Qun's seventh uncle?

Zheng Wanan. Uncle Qi was arrested and never thought about going out after he entered the secrecy bureau. Commissioner Cheng discussed with Cao Shun and took her back to Guizhou to meet her parents. This is her last reunion with her family. Her original name was Zheng Qun, and her father was Zheng Wanan, a famous anti-Japanese. Commissioner Cheng hopes that General Zheng can persuade him to "change his mind" and tell the secret in her heart.
