“囧”This is very popular right now. because the work is really interesting like a morose face. People like to express their feeling by it.

I told you some simple expressions. 神马都是浮云 that means don’t take things too serious. All things are of no consequence just like floating clouds。 给力 in english we call it gelivable. a new word. it express great or wonderful and so on. it is just a interjection.

杯具=悲剧 洗具=喜剧 小朋友=小盆友 can you guess?it's very interesting!!

Xenophile: if u won't live in china for a long time, you neednt learn such slang. cause no chinese people will use slang to you, they know you wont understand, most of them just speak Mandarin. it is alike if i go to America for a short time. so just spend least time to do most things learning a foreign language is to use it to communicate, not to waste your time. and every year and every city in china there have a lot of slang.

yeah.there are also lots of alang in Chinese.Like 放飞机(放鸽子），It means you have an appoitment with someone(you say yes) but you don't get there(even you have something very important,and have to leave)So we can say 你放我鸽子 By the way.我想跟你做个朋友，可以吗？
