Can I take the subway when Health Treasure is overdue?

I can't. According to Beijing's epidemic management regulations, the results of nucleic acid test displayed on Beijing Health Treasure must be within three days before users can enter public places such as subways. Therefore, if the health treasure expires, the staff will not allow users to enter the subway. Health Bao refers to Beijing Health Bao. It is a small program that is convenient for individuals to inquire about their own health status related to epidemic prevention, and all personnel in Beijing and entering (returning to) Beijing can use it.
