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

 Indah Kurniawati:

Love in Time - time travel (there's a suspicion of cheating but actually none)

Ode to Joy - friendships circle (the first two season, i can't remember about cheating though since it's an old drama)

Flight to You - pilots story

Surgeons - hospital industry

You are My Glory - typical Gu Man's sweet love story

First of all Thanks for Recommendation.

# About Love in Time, the Casts seem Younger than I am looking for...

# Ode to Joy - I have already watched the 2016 Ode to joy

#  Flights to you - I will put this on the list  even  though Airport, Pilot story is not my thing unless it TOPGUN

# Surgeons- Now I love Hospital drama and the Cast seem mature exactly I am looking for so Might give this one a try

# You are My glory- Watched it already, enjoyed it but again I am looking for Kinda Older casts.

Once again, Thank you for your recommendations
