In this paper, I consider one of the schemes of doctrinal classification proposed by Xingman 行滿, a disciple of Zhanran 湛然, in his Compendium on the Teachings of Tiantai Buddhism 學天台宗法門大意, and conclude that Xingman’s classification is a typical example of the doctrine shared by Zhanran and his disciples as the doctrine of Zhiyi 智顗.
