Two Standard Scripts, One Language
Simplified Chinese is the official script of mainland China and Singapore. Traditional Chinese is standard in Taiwan, Hong Kong and Macau. They are not different languages: the grammar, pronunciation and vocabulary are overwhelmingly the same.
How Characters Were Simplified
The 1956 and 1964 reforms simplified around 2,200 characters. The changes follow recognisable patterns, which makes reading the other script a learnable skill rather than a second language.
Radicals are the shortcut
Learn seven simplified radicals — 讠 纟 饣 钅 门 马 鸟 — and you can decode a large share of traditional text on sight, because you already know the meaning of the full form.
Which Should You Learn?
If you have no strong reason, learn simplified: it has fewer strokes, more学习 material online, and the HSK syllabus assumes it.
Learning to Read the Other Script
Conversion is mostly one-directional in practice: simplified to traditional has more ambiguity, because several traditional characters can collapse into one simplified form. 发 covers both 發 and 髮.
What This Means for Exams
HSK is printed in simplified characters and expects simplified in the writing section. TOCFL, used in Taiwan, is printed in traditional. Mixing scripts in a written answer counts as an error even when the character is correct.
FAQ
Are simplified and traditional Chinese mutually intelligible?
Yes, in writing, once you can read both scripts. The grammar and vocabulary are the same, so a reader of one script can usually follow the other with a few weeks of conversion practice.
Which is older?
Traditional characters preserve forms in use before the twentieth century reforms. Simplified characters were introduced in the 1950s and 1960s in mainland China, and many simplified forms actually come from older cursive handwriting rather than being invented.
Can I use traditional characters in the HSK writing section?
No. HSK expects simplified characters throughout, and a traditional character is marked as an error even if the choice of word is correct. Practise in the script of the exam you are sitting.
Is it worth learning both?
Eventually, yes — being able to read both opens a much larger range of books, media and websites. But start with one, get to intermediate level, then add the other through reading rather than through a second beginner course.
Next Steps
Whichever script you choose, the characters themselves are covered in Chinese radicals and stroke order. For a plan, start with HSK 1.
