The following is an analysis of your situation:
BC 10008 couldn't get a ticket if I tried to buy a high-speed rail ticket before.
Reason:
After a series of telephone consultations and online surveys, I found out the truth of the matter. At present, the epidemic prevention of big data is still immature, which leads to frequent "accidental injuries". That is to say, you have all kinds of green codes and have never been to or passed through medium and high-risk areas. However, due to system errors, you will be restricted from entering Beijing, and Beijing Health Bao will have a pop-up window.
Solution:
Call the Beijing citizen hotline 12345 directly, truthfully explain and report your situation, and they will report your situation to the relevant departments and wait patiently. After the relevant departments have verified that it is correct, the restrictions will be lifted for you, and Health Treasure will restore the green code.
