First of all, we must see if people can get out of Haizhu District. If they can&;t get out, they will definitely not be able to return to Yulin. If you can walk out, will the health code turn yellow or red? If you change the code, you can&;t go back to Yulin. Given the seriousness of Haizhu at present, if you go out forcibly, you may bring the source of infection! If you are unfortunate enough to infect others with the virus, it is a crime!
