Yang Yi
Wei Yan and Yang Yi separately wrote memorials to the Shu imperial court to accuse each other of treason. Their memorials arrived in Chengdu on the same day. The Shu emperor Liu Shan asked the ministers Dong Yun and Jiang Wan for their opinions. Both of them sided with Yang Yi and felt that Wei Yan's actions were suspicious. In the meantime, Yang Yi ordered his men to cut down trees to rebuild the gallery roads, and his troops marched day and night to catch up with Wei Yan. Wei Yan arrived at the southern valley first and ordered his soldiers to attack Yang Yi. Yang Yi sent Wang Ping to resist Wei Yan. Wang Ping shouted at Wei Yan: "His Excellency (Zhuge Liang) had just died and his body had yet to turn cold, and now you dare to do something like this!" Wei Yan's men knew that their commander was in the wrong so they deserted.
