Shall I quit academia or continue doing research without too much luck?
You write "My life already suffered from my research career." This is worrying.
Think about this: what do you need the most for a satisfying life? Is it being close to home? Having a fulfilling relationsship? Having a garden? Living in China? Living near the sea? Being a researcher? Find out what it is for you and focus at first on that. Then find out what else you can do while realising your first priority.

Don't get too hung up on Academia. Being a researcher is not a higher calling from some God, at the end of the day it's just a job. There are many good and satisfying jobs out there. Find out what else the world has to offer.
