Written Chinese comes in two basic forms: Traditional and Simplified.
Traditional is the “original” standard form and is used today in places like Hong Kong and Taiwan.
Simplified Chinese was invented in the late 20th century and is used in Mainland China.
This site primarily uses Traditional Chinese because:
1) Traditional Chinese characters have a logic to them that gets truncated in simplified,
2) Traditional is what we learned when we were first starting out,
3) The majority of the songs covered on this site are by artists from Traditional Chinese-using places,
4) It’s easier to understand Simplified Chinese when you understand Traditional,
5) and several other reasons, which you can read about here 🙂
That said, feel free to use whichever writing system you prefer. You can always use Google Translate to switch between the two! (That’s what we do)
