Is the whistleblower Zheng Tuo a good person?

Informer Zheng Tuo is a good person. Zheng Tuo is the illegitimate son of Lao Zuo in the TV series "The Informer". A young man who likes photography is neither an agent nor a spy. Zheng Tuo likes pigeons, but his father, Zhen Lao Zuo, once had a brief love affair with pigeons. Because Du Shengkui wanted to find a spy to replace Zheng Tuo's father, Zheng Tuo and his son had to be eliminated.
