After working abroad for several months, do I need a visa to return to China now?

You don't need a visa. According to the enquiry of China Travel Service. Com, as of April 25, 2023, you have a work visa to work abroad. Generally speaking, a work visa is multiple round trips. To return home from abroad, as long as you are still a China citizen and hold a China passport, you only need to show your China passport. If you go abroad without a passport or if your passport expires, you can go to China's embassy abroad with a legal citizenship certificate, then apply for a temporary travel document and buy a plane ticket to return home.
