Mid/end June 2022 now and it seems China gained control with low daily numbers.
Now, mid April 2022 the opening situation looks worse than ever.
Now, 3 month later no change for the border situation, but many changes in Hong Kong and China.
As of today, Dec. 20th 2021 the Hong Kong-Shenzhen border is still closed to people without any special visa.
Border opening plans are getting more detailed. Looks like from December limited number of people can enter daily.
There is some talk going on about opening the border - for business travellers - but that is a start.
Sadly, a no update update. It’s September 2021 and the border is closed for most. This effects tourists, business visitors and most normal people, including all Hong Kong residents.
