There will be changes. You need to log in to Health Bao to fill in the information yourself, otherwise you need an accident health code to go to parks and other places. For example, if Beijing has been to other places, after you come back, scan the code in the park to show which cities you have been to. If there is nothing unusual, there will be an upward green tip. This is the new health code. When you fly to the airport, you will be asked to scan the code to register which city and which specific address you are going to, and then what to do and other detailed information before boarding. For example, Beijing goes to Yunnan. After landing at Kunming Changshui Airport, you need to scan the local health code when you leave the airport. Only with the local health code can you leave the airport. Then you need a local health code to go to high-speed railway station. For example, if you fly to Zhengzhou in Yunnan and get off the plane in Zhengzhou, you need to scan your ID card to register. You will be given a green bracelet when you leave the airport, which means that you are healthy from other provinces to Zhengzhou. Then Zhengzhou returned to Beijing, and the Beijing health code on your original mobile phone has changed, so there will be no pictures immediately. You need to enter and fill in the city information you have been to within 14 days. At this time, health treasure may be , and the information registration cannot be refreshed. Go to the park. Some parks need you to show your health code, so you need to ask him to scan another code for you. If you have been to other places, a green tip will come out when you scan it, showing all the places you have been in 14 days. Then, after 14 days, your Beijing health code returned to the one with a picture.
