Story:
Wu Zixu spent the night in Zhaoguan, his head was white. Zixu is the second son of Wu She, a doctor of Chu State. King Chu Ping acceded to the throne, a luxury teacher. Ping Wang listened to Shao Shi Fei Wuji's slanderers and was killed. Zixu escaped. King Chu Ping ordered the painting of shadows and figures and arrested Zi Xu everywhere. Zixu first went to Song, but because of the Song chaos, he went to Wu, passed by Chen, went east for a few days, and went to Zhaoguan (now north of hanshan county, Anhui). Zhaoguan is between two mountains, and there is a big river in front. The situation is dangerous and heavily guarded. It's really difficult to get through customs. It is said that Wu Zixu went through Zhaoguan, where it turned white overnight. Thanks to the ingenious arrangement of the famous doctor's disciple Dong, Wu Zixu got through Zhaoguan and came to the State of Wu. In Wu, he assisted He Lv, the king of Wu, and Qiang Bing, a rich country. Cutting Chu, attacking Chu Du Ying (now Jinan City, Jiangling, Hubei Province), Ping Wang died, and Zi Xu dug a grave and whipped his body for 300 times to vent his anger. After Fu Cha, the king of Wu, acceded to the throne, Zixu became a general and defeated the Vietnamese army in Fujiao (now southwest of Wuxian County, Jiangsu Province), making great achievements.
