Ji Kang
Yang Jun (d. 291) was a Jin Dynasty (266–420) official during the reign of Emperor Wu and regent for Emperor Hui. Sun Deng's "death" and reappearance is typical for Daoist "shijie" 尸解 "release from corpse" fake burial, the lowest level of "xian" "transcendence". This "grave affair" refers to Ji Kang getting involved in Cao Wei court politics, and sentenced to death by regent Sima Zhao for testifying to help a friend.
