This tutorial will help you switching Ubuntu user interface language to Chinese (汉语, Hànyǔ or 中文, Zhōngwén). We offer you both choices of Simplified (简化字, Jiǎnhuàzì) and Traditional Chinese (正體字, Zhèngtǐzì). This will change the language of basically everything you see on the screen including login screens, menus and buttons, calendar and locale / regional format. For example, once switched you will immediately see Files, Writer and Clock all turned into Chinese characters. We also included a procedure to revert back to English language in case you need it. Finally, we write this as an aid for our friends Ubuntu computer users whose language is Chinese everywhere including China, Hong Kong, Indonesia, Macau and Taiwan.
