What are you trying to get done?

As for your question, there are some upwork type websites but I am not sure of the quality. You have to vet your counterparties very carefully here as schemes and frauds are enormous. As a legit company it took us quite a while to convey legitimacy and foster trust.

I run a professional services firm in Shanghai catering to job seekers. Reach out to me by my profile email. TIA.
