Hello, I want to ask why Zhengzhou Library can't make an appointment. The reason why Zhengzhou Library can't make an appointment is that

1, abnormal body temperature health code;

2. From middle and high risk areas. Zhengzhou Library stipulates that readers in middle and high risk areas are not accepted, and the temperature health code is abnormal. Zhengzhou Library will use the platform of "Henan Wenlvtong" to make an appointment. Readers can make an appointment online or scan the code on site through the WeChat subscription number of Zhengzhou Library. Those who have not made an appointment cannot enter the library.
