Wang Jun, who runs a marriage guidance consultancy in Yancheng city, Jiangsu province, is an experienced marriage counselor, but when people ask about her job, she always replies that she is a "doctor".

"When people come to consult me about their marital problems, I often see myself as a doctor because, in my opinion, a marriage with problems is just like a person who has fallen ill," she said.

"I listen to their problems patiently, uncover the fundamental reasons for the problems, inform them of the hazards they will face if they divorce, and put forward my suggestions. It's similar to the process by which a doctor diagnoses an illness."
