Hi @junlinpiao123
Please make sure that your site is using https before integrating with WeChat (whether with WP Weixin or any other component).
Please also make sure WordPress is configured properly: the URL within the QR code displayed upon visit of the site is an IP address, where it should be a proper subdomain.domain.tld URL.
Thank you for your note.
I am not using https, I am using http.
Is that a problem?
Do I have to use https in order to make WeChat work properly?
and I have a domain and connected to my server.
but I already have installed wordpress before I bought a domain and so my wordpress website is still using IP address.
In the wordpress database, the site url is still with IP address.
Do I have to reinstall wordpress on my server?
I have registered as a wechat developer account. so I have App ID and App Secret.
I have a domain and it is licensed with ICP.
I have installed wp-weixin plugin.
What else is necessary to make wp-weixin work properly?

Yes because WeChat requires it.

You do not have to reinstall WordPress, you have to change the Settings > General > WordPress Address (URL) and Site Address (URL) fields with the domain.
How to configure WordPress and https is out of scope of the support for WP Weixin.

I have installed wp-weixin plugin.

The list of requirements is outlined on the plugin description page. A WeChat Developer Account may not be sufficient.
The plugin is designed to work with a certified Official Account, and different types of Official Accounts have different access to features.
For example, identification requires a Service Account.
See this table for information.
Support on this forum is provided for bugs only, and your issue is with configuration. I will make the topic as resolved.
Did you try wechat login in my website?

Unable to log in WeChat
