Is China now open? I have a visa issued in 05Oct2015, but expires 05Oct2025.

I am married to a Chinese citizen. My wife is in China right now. I have a Chinese 10 year multiple visit visa (L) for 90 day stay and it expires 5Oct2025, it was issued 05OCT2015. I hear China is now open do I need to renew the visa, it has not expired? Is it correct China now open? What are current requirements to travel to China?
