According to traditional history of Ju-kyo, Do school was not active in Chin, and it was first handed down to the north when Cho Fuku, who became a captive in Mongolia, passed it to Yo Su (Yao Shu) and O Ichu, but today, it is known that the Do school was active in Chin.
伝統的な儒教史では、金では道学は行われず、モンゴルの捕虜となった趙復が姚枢・王惟中に伝えたことによって初めて道学が北伝したとされたが、現在では金でも道学が行われていたことが知られている。
