Yu was the family-minister of Fan Jishe and Zhonghang Yin who were two of six influential ministers of the Jin State.
Yu Rang knew Zhao Xiangzi would recognize him if their paths crossed again, so he disfigured himself by having his skin covered with lacquer to create scars and sores.
[1] A friend of his was worried about Yu's plans and tried to persuade him to choose another approach to achieve his mission: "You have many abilities and you can serve Zhao Family.
When Zhao Xiangzi made his way over the bridge, his horses were suddenly startled as Yu Rang approached.
Zhao Xiangzi interrogated him, and Yu Rang explained that it still was his duty to avenge his former master Zhi Bo,[3] even though he personally had nothing to gain from doing so.
Zhao Xiangzi sighed and was moved that Yu Rang was still being loyal to Zhi Bo.
Yu Rang stabbed the robe three times, crying to heaven that now he was ready to report in front of Zhi Bo.
After his death, Yu Rang's story spread throughout China and Japan, and people were touched by his loyalty.
