This saint aims at educating people to be law-abiding.

Zhou Yafu has a mountain of discipline.

Zhou Yafu was an outstanding general in the Han Dynasty. He was famous for his bravery, being good at fighting and strictly observing military discipline. On one occasion, Emperor Wen of the Han Dynasty wanted to reward the army in person, and first went to the barracks stationed on Bashang and Ximen. Wendi and his party rode straight into the camp, and the general and his party rode off.

Then, Wendi Deng came to the military camp in Liu Xi, where Zhou Yafu's army was stationed. I saw soldiers in Liu Xi camp wearing armor, holding sharp weapons and full crossbows. Wendi's vanguard arrived and wanted to go in directly, but was refused by the guards at the camp gate. Pioneer said: "The son of heaven is coming soon!" A captain of the military gate guarding the camp gate said: "The general has an order:' The army only listens to the general's orders and does not listen to other instructions.' "

After a while, Wendi arrived, but he still couldn't get into the barracks. So Wendi sent an emissary with Jeff to tell the general, "I want to go into the barracks to comfort the army." Zhou Yafu delivered the order and said, "Open the barracks door!" The officer guarding the gate of the barracks said to Wendi and his party who were driving and riding horses, "The general has a rule: horse racing is not allowed in the barracks." So Deng Wendi and others pulled the reins and walked slowly.

As soon as he entered the barracks, Zhou Yafu bowed to Emperor Wen with a weapon in his hand, saying, "A warrior in armor can't bow his head. Please allow me to see your majesty with a military salute. " Wendi Deng was moved by him and her expression became serious. He held the crossbar in front of the car, thanked him and said, "The emperor respects the general!" " Don't leave until the ceremony is over.

Out of the camp gate, all the ministers expressed surprise. Emperor Wen said, "Alas! This is the real general! The troops passing in front of Bashang and Zhaizhai are like children's play, and those generals can easily capture them by surprise attack. As for Zhou Yafu, who can offend him? " After that, Wendi continued to praise Zhou Yafu and ordered a big reward.
