can someone explain what don't close mountain means?

I wanna now too

mountain i think has something to do with his name. they were making fun of him cuz of that name long ago.. i cant remember which chapter, but even that doesnt explain the dont close bit.. maybe he was telling him not to close something simply? msg or phone haha im curious too

"Don't close mountain" is the English transliteration of name "Mo Guanshan". It makes no sense in English and is a rather strange name in Chinese too.

He Tian gave him this nickname and "Little Mo" even <3

that makes much more sense haha i was like he tian, you're being a bit cryptic
