Can my wife who is a Chinese citizen and I who is a US citizen travel to China in late December.

I have 5 years remaining on my 10 year China visa. However. I was told that due to COVID-19 that I must apply for a new visa. Is this true or is my old visa with 5 years remaining good to use? Can my wife who is a Chinese citizen and has a permanent resident green card and I with my USA passport travel to China in late December. I do not know the current rules of travel to China. We would learn from Chicago.
