me and my boyfriend overstayed in china for 20 days, can we still work in china? thank you.

it happens that, out employeer didn;t help us renew another 6 m0s or 1 year visa, 3 days before the expiration. . . he told us it's ok, but it's not, and we are force to leave china within 10 days. so, can we stilll come back and work there? thank you
