LeetCode links

First of all, thank you so much for this wonderful repo, and also sorry for asking my question in English as inputting Chinese is too painful for me.

My question is actually not necessarily related to this repo, so please forgive me for posting such question here. I'm a bit confused regarding the leetcode links provided in this repo. It seems that the links point to the Chinese version of the leetcode site correct? What's the relation between the Chinese version site and the English version site? I ask because I'm a regular user on the English leetcode site, but I found that I wasn't able to login to the Chinese version site with my English site user name and password.
