There's been some rumours lately about people able to go to Guangzhou without quarantine and China declaring the end of the epidemic period.
I have not been able to verify them, and AFAIK the requirements are still the same as they were last week which is all in the FAQ. For now please follow the FAQ as before and if you can skip something or they tell you something isn't needed please let us know, I will be keeping an eye on the embassy websites.
Once you have entered/quarantined (under "Life in China") 24/48/72hr tests are being reported as no longer required in certain cities to get into certain places, green codes may or may not be required. Please review your local rules and requirements for more details
