Eight ranks, one standard.
Rank is not decoration. Each belt raises the bar on both speed and accuracy, and the app never hands one out for showing up.

The training · 稽古
How the practice works
01
Choose your belt
Start at white. Every belt sets a stricter standard for speed and accuracy than the one before it.
02
Land ten clean strikes
Ten correct answers in a row. A careless miss resets the streak — the belt has to mean something.
03
Advance your rank
Rank up, unlock the next belt, and keep the practice short and daily rather than long and rare.
