同学Classmate or schoolmate
"Tong xue" means "classmate" in English. So if someone refers to you as their "tong xue," they're basically saying you're in the same class as them. Hope that clears things up for you!
'Tong xue men hao' (同学们好) literally means "People who learn with you, hello". But teachers can say it to their students as "Hello, students." As well as students can say it to their classmates as "Hello, classmates."

Oh, dude, when someone says "tong xue men hao," they're just saying "hello, classmates" in Mandarin Chinese. So, like, you could totally respond with "ni hao" to keep the conversation going, or you could just nod and give them a little wave if you're feeling lazy. It's all good, man.
