Looking for a Mature Chinese Drama( where the characters are Mature)

Well I am looking for a Mature Cdrama where the characters are not College level or sort. If anyone has seen Korean Drama, Gentleman's DIgnity. I am looking for drama like that where the characters actually look and seem mature. I know there's like a Chinese Remake of it or some sort, I couldn;t finish that one.

Also Plz No cheating because Lately My YT has been filled with OLD OLD Cdrama of Female Leads cheating
