Can Suining's health certificate be used in Chengdu?

The health certificate is valid for one year, and it will be invalid after one year. Generally speaking, it is divided by provinces, autonomous regions or municipalities directly under the central government. Therefore, the health certificate issued by the municipal and county health administrative departments is no problem in this province, but it may be biased because of different local regulations when it is implemented in different provinces. I hope my answer can help you.
