What is Tan Yaozu's identity?

Special agent. Daddy Daddy Daddy is an anti-war drama produced by Shanghai Ciwen Film and Television Communication Co., Ltd. and directed by Yu Min. In the 26th episode, Tan Yaozu secretly met Su Mingyuan. He deliberately pretended to care about the case of losing medicine and asked Su Mingyuan if he had found out the mole. Tan Yaozu is nominally an important official in Nanjing, but in fact he is a special agent sent by Chongqing to investigate the disappearance of penicillin. Su Mingyuan said that he is investigating this case himself. When the investigation is clear, he will definitely return to Chongqing to report to me personally.
