"Diamond skin" is covered with Henan Health Code. Click on the official account of Henan Health WeChat, click on "Medical Health" on the menu bar, and then click on the health code to unlock the "diamond skin" after the COVID-19 vaccine is strengthened.
This kind of "diamond skin" refers to the precise and hard edges and corners of diamonds combined with the "Erqi" memorial tower and peony flowers as creative elements, which are tall and straight. For example, hard diamonds closely surround the health code, just like COVID-19 vaccine protects people's health and resists virus invasion and infection, which means to build an immune barrier and protect people's health.
