Do you ues Wechat? In China, Wechat is the most popular smartphone messaging app, most Chinese use it to contact friends. As far as I konw,people are like to use "Skype" or "Line" to contact others, right? There are barriers named "Great Firewall of China" between China and other country, so it's always diificult to communicate with people from other country, and it make me feel a little unhappy.So guys, if you want to learn Mandarin and Chinese culture, or just have some questions about China, please feel free to message me, by Wechat is better.
