Why is Tianfu health code online again?

Recently, a new case of COVID-19 epidemic occurred in Sichuan. In order to strengthen epidemic prevention and control, the Sichuan provincial government decided to re-enable Tianfu Health Code. According to the query of Sichuan Big Data Center, Sichuan Tianfu Health Link was upgraded at 10: 30 on the evening of October 4th1/kloc-0. In the scene of scanning location codes in the past, we need to do two things. One is to take out the health code, read the nucleic acid and the living history of the risk city, and then scan the place code. People have to do two steps and the staff have to check it twice. After the upgrade, the people only need to scan once, and the staff only need to look at it once.
