I'm not happy
In the China, students have many a lot of homework. They don't have free time on the weekend. They must to learn Chinese, Math, English, Physics, Politics, Geography, Biology, and History. They don't have friends [1]. They don't have partys parties. They just have classes, teachers, notebooks and their homework!
----
[1] I think you mean, "They don't have time with friends."
Please add a space (' ') after every comma (',') and full stop ('.').
你好, 你该改 partys 成为 parties; class,teacher 成为 classes, teachers 来表达你自己有很多课程,每个课程也有不同的老师. 还有, 没有 must + to V, 而是 must + V => Must learn.
只在帮你改改, 没什么意思,希望你快完成功课吧! 很高兴如果可以啃你交个朋友, 谢谢! 晚安 ^^
