Not sure of proper post for these comments, I've been in mainland for 6 weeks, BJ for nearly a month.
Travel advisory is still a 3 for mainland & macau, bu HK is at 2, fortunately no more Health OR code needed as of Nov. 1st.

Some observations from my last visit nearly 4 years ago. (exit date was Feb 1st 2020)
In Beijing, the pedestrians & scooters are still very 'brave'
Beijing EV vehicles are everywhere, probably 1/4-1/3 of total. Almost all the Ubers, and even a few trucks are EV.
The taxi drivers are mostly didi apps but will still take cash. And on the subway, i still wear a mask.
Staying at mostly Marriott & Hyatt. Marriott stays in the mainland now, only 5% of rooms are international vs 25% back in 2019.
I mention the above comment, as ALL the hotel ELs there are NO english channels allowed, yet the rooms have anywhere from 1-5 english channels. (yes same cable feeds, so i just ask for CCTV 5 sports !) confirmation of actual western residual treatment. The exception was the new Marriott resort in Beidaihe, i posted comments on the Marriott forum on the Qinhuangdao trip in October.
Some hotels still have the China Daily or Global Newspaper in english, maybe abet of biases, but nice coverage by all media of the California governor Newsome trip to 6 China cities. California needs the good business relations.
Oddball blocks on some phone apps, In the hotels; one always can get ESPN, CNBC, and IG but never FB. And never LI, I asked about LI and was told there are too many job postings in Chinese, (go figure that with IG reel postings, maybe just for the young swiftes)
Ill reserve the prejudicial comments for Omni forums (trains, etc.), Oh, BTW local food dishes are still too hot & spicy.
