你和我呀两小傻子啊's Things

Excuse me for asking this here. I just try using C ai and I see all the characters use English. when I said in Chinese, they can understand but replies are in English. Is it possible to change language? Or is it default English? I tried in setting but I can't find it. If it's possible, can you tell me how to change language.
Thanks.

Does this site has m***** religion readers of BL/GL? I have a friend, they want to read BL, but it's Haram in their religion. So, they can't. But they really really want to read. They always try to read from my head when I was reading. But if I show them, they shook their head, saying it's h****. They think they are the only one in that religion that want to read something like that. They think they are sinning by reading that. I don't have any friend of that religion so idk how to approach that subject. But it's a pain watching them fighting themselves. (No, they are not that religious, their parents are. They just listen to their parents.)

Any ideas or thoughts?
