Trying to figure out, if I had to separate Chinese into 6x10 = 60 levels, just like https://www.wanikani.com, how would I do it?

My current answer is, follow the textbooks and HSK, and sometimes, wordfreq and junda (but secondarily).

See my current answer here.

I have compiled to Anki file (*.apkg) here.

• Learn Hanzi in Textbook/Sentence-learning order. Only if both of the following not available, sort Hanzi by frequency according to Junda.
• Learn Vocab on EN->ZH regardless of whether you know the Hanzi or not, but prioritize the Hanzi you know first (if the vocab does not exceed the HSK level you are supposed to know.)
• Learn Vocab on ZH->EN only if you have already know the Hanzi (that is, Hanzi in this level, or in previous levels).

• Vocabularies, probably broken down jia jieba, can be added to Anki deck / default profile, via this script.
