Hello everyone! This is LuoKeying or lain(in short). I'm an English lover and want to learn a lot of english! And I'm also an undergraduate majored in science.

I play HSR, Reverse:1999 and some other video games.

回复 @罗可盈：Btw, could anyone tell me how to edit my avatar? I am a little dumb with that lol.

回复 @啊啊是谁都对：THANK you for your advice, I'll try it then.

回复 @啊啊是谁都对：Thank you thank you! Now I think I may have solved this problem with your precious assistance. Sorry for not replying to your post for such a long time because I've been very busy these days, too many lectures to attend and experiments to do... :(
