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

Are you my hero

My dear guardian

FL are over 30 in both series, but not sure about ML.

There is also Blossom Shanghai 

If you like hospital/medical dramas, Dr Tang was quite good imo
