I feel your pain too, I currently have a trip planned to Shanghai, Beijing and Hong Kong in mid-April but it's starting to look like this may take at least a few months to be at a point where tourist attractions/internal travel are open properly. I think it's best to wait until mid-Feb onwards...
I just returned form a short trip a couple of weeks ago and had a 50% success rate with being able to park at various resorts to look around. I tried 6 resorts on a Tuesday and could park with no issue at 3. It was pretty busy on the roads and in the car parks so I would assume it now completely...
