If you travel to and from Beijing and Tianjin on the same day, Health Treasure will not pop up, but you need to do another nucleic acid test within 72 hours. You need to go to Beijing for treatment whether you go back and forth on the same day or the next day. If you don't do the nucleic acid test within 72 hours, Health Bao will pop up a reminder to do the nucleic acid test. After the health treasure pops up, it can't be used, which will affect your travel.
