Tianfu Tong's health code shows that he stayed in Sichuan for 5 days. What does that mean?

Tianfutong health code shows that the health code holder arrived in Sichuan Province in less than five days. The entry information displayed on the Tianfu Tong health code is to remind the returning personnel to complete the "entry inspection". If you have been in (back to) Sichuan for less than five days, "Less than five days in Sichuan" will be displayed in the interface of "Tianfu Tong Hygiene Code", and you need to do three inspections in five days, otherwise you will be labeled with a yellow code.
