Once you understand tones, you are ready to begin learning oral Chinese words.
Unlike many other Chinese learning platforms, this site does not teach PinYin in a standalone way. Rather, it is expected that you will learn PinYin naturally as you see examples and hear how they are pronounced — you can learn all of PinYin this way, and it’s more natural and easier to remember the various pinyin pairs.
The format of this section of the website is simple: you learn words, one by one, and whenever you learn a new word examples (sample sentences) will be built around the new word you are currently learning as well as older words which you have already learnt (as practice).
Thus the language is learnt, one word at a time, with practice to learn how PinYin works and grammar rules through natural language examples.
