Yunnan, the first province to use health codes.

Hello, would you like to ask which province in Yunnan used the health code first? The province that used health codes for the first time was not Yunnan. Because the health code was first used in Hangzhou, on February 1 1 day, 2020, due to the novel coronavirus epidemic, Hangzhou, Zhejiang Province took the lead in launching the "health code" model, and implemented the dynamic management of "green code, red code and yellow code" for citizens and people planning to enter Hangzhou. Therefore, Yunnan was not the first province to use health codes.
