Chongshan Town, South Route, Dingliao Guard.
The Assistant General of South Route Dingliao Guard is Cui Chengwu, who was chosen by Qin He as his successor, but he is also a close confidant of Yang Chengye.
Cui Chengwu is Qin He's son-in-law. When Qin He was still serving as the Assistant General of South Route Dingliao Guard, he was delegated to Yang Chengye's command.
Yang Chengye has been stationed in Chongshan Town for over twenty years, and Cui Chengwu has been by his side for more than ten years. It was only after Qin He aged and retired to return home that Cui Chengwu was appointed as the Assistant General of Dingliao Guard by Yang Chengye.
In Chongshan Town, from various Assistant Generals to mid-to-high-level Military Officers, they all seem to be a network of connections, each with ties to the Yang family or with distinguished identity and background.
This seems to be an unfair display, but in reality, it is a very fair outcome.
