- Master Yinzhang and Master Er delivered a letter from the Commander to the Master. The Master replied with a letter, and at the end of it, he drew two feet. Beneath the feet, he wrote the names of the two masters and sent it to the Commander. The Commander then replied with a verse. (因章介二大師持都尉書至師師有書復於書後𦘕兩隻脚脚下書二大師名寄都尉都尉復以頌答)
