Beijing health treasure green code, but restricted to buy tickets to Beijing. Can I take a taxi in Hebei?

You can't. "Beijing Health Treasure" is a small program that is convenient for individuals to inquire about their health status related to epidemic prevention, and can be used by all personnel in Beijing and those who enter (return to) Beijing. You can't take a taxi after buying tickets to Beijing. You can't go in until you get back to normal. People in the green code can't buy tickets to Beijing because of the epidemic.
