Zhao Chengping is the Deputy Chief of Staff and Shen Hanyang's nemesis. He received an anonymous letter about Bai Yue and Jia Peng's relationship and acted quickly on it. Shen Qingjun wrote the letter to him intentionally to stir trouble and ensure Shen Hanyang and Bai Yue's countryside days would not be as comfortable as in the book. Only in his hands could the letter have the greatest impact. It wouldn't overthrow Shen Hanyang but could cause significant trouble.
