Wang Dao
In 372, Emperor Jianwen grew ill, and he issued four successive edits summoning Huan to the capital—a strong indicator that he was willing to yield the throne to Huan—but Huan declined each time, apparently believing that the edicts were a trap. Indeed, Emperor Jianwen initially drafted a will that stated, "The Grand Marshal Huan Wen shall be regent under the precedent of the Duke of Zhou," and "If the child can be assisted, assist him; otherwise, take the throne yourself," mirroring language that Liu Bei, the founding emperor of Shu Han, used when entrusting his son Liu Shan to Zhuge Liang. With Huan not in the capital to affirm it, however, Wang Tanzhi persuaded Emperor Jianwen to tear up the will and rewrite the instructions as, "All major affairs shall be submitted to the Grand Marshal, under the precedents of Zhuge Liang and Wang Dao," greatly reducing any legitimacy Huan might have if he should try to take the throne.
