Who knows about "goat-left friendship"?

"Goat Left Friendship", an example of sacrificing one's life to help a friend.... "Sheep left", that is, sheep horn mourning and left Bo peach. Both of them, are people in the Spring and Autumn period, Zuo Botao has "the talent of the world", but nearly forty years old, is still not a success and fame. I heard that the king of Chu "recruiting", he braved the cold, snow and wind to run to Chu, on the way to ask for accommodation in Yangjiao woe, by Yangjiao woe warm reception. That night, the two sleep against their feet, *** talk about the chest of learning, talk very much. The next day, they became brothers. And decided to go to Chu together to seek fame. Who knows that the sky is not beautiful, all the way, first of all, rain and do difficult, after the snow and wind to block the road, they are thin clothes, with dry food and not much. In this case, Zuo Botao thought, if two people are going to Chu, then both can not go, a person alone, there is still hope. So, Zuo Bo Tao took off his clothes to Yang Jiao Sheng and forced him to go alone. Sheep Horn Sorrow firmly refused to do so, and also wanted to take off his clothes and give them to Zuo Bo Tao, so that Zuo Bo Tao could go to Chu alone. While they were arguing, Zuo Botao died of gas because he could not stand the cold. With infinite grief, he took the clothes and food, and left with sadness and weeping. After getting an official position in the state of Chu, he immediately returned to the place where Zuo Bo Tao froze to death and buried his body. Thinking of the past incident of "taking off his clothes and food", he decided to cut his own throat, and had his tomb placed next to Zuo Bo Tao's. This is what is known as the "Tomb of Zuo Bo Tao", and it was the first time that he was killed. This is what is known as the "sheep left the friendship".
