The Chinese Catalogs Are Missing

[worranhin]

I noticed that at the main page, the Chinese catalogs are missing (show as below), while other language is displayed properly. However, if I enter the URL directly (like https://runebook.dev/cn/docs/angular/-index-), I can go to the exact page.

I wonder is it something wrong with the website, or it is because of my network connection problem.

It would be of great convenience if this can be fixed. And thank you for your work sincerely.
