URL修改如何使用多域名？

I have the first Chinese language, and the binding URL is https://www.yantuo.com.cn

I want to add some new language support, but I made an error in configuring the environment. I don’t know what to do.

Error location:

Language is set according to the linked secondary domain name：
https://en.yantuo.com.cn/my-post/

Polylang was unable to access the https://en.yantuo.com.cn/?deactivate-polylang=1 URL. Please check that the URL is valid.
Polylang was unable to access the https://zh.yantuo.com.cn/?deactivate-polylang=1 URL. Please check that the URL is valid.

I configured in wp-config.php:
define(‘WP_ALLOW_MULTISITE’, true);
define(‘MULTISITE’, true);
define(‘SUBDOMAIN_INSTALL’, false);
define(‘DOMAIN_CURRENT_SITE’, ‘www.yantuo.com.cn’);
define(‘PATH_CURRENT_SITE’, ‘/’);
define(‘SITE_ID_CURRENT_SITE’, 1);
define(‘BLOG_ID_CURRENT_SITE’, 1);

The domain name also resolves to the server, which also binds the directory.

So I don’t know how to configure the idea of multi site and multi language?

Can you help me?
