I was only crowned marquis, but you directly claimed the title of king, and from then on we broke off relations
Ancient people generally attached great importance to brotherly feelings, interacting with friends, to have faith in words, but also to trust each other, so that brotherhood can last forever.
At the end of the Qin Dynasty and the beginning of the Han Dynasty, there were two more famous people in the State of Wei, namely Zhang Er and Chen Yu, who claimed to be friends of the neck, that is, the friends of life and death, but in the end because of mutual suspicion, mutual jealousy, and even broke off friendship, cannibalism, and finally Chen Yu died under Zhang Er's knife.
In the past, Zhang Er and Chen Yu were both Chen Liu Da Liang people, their experiences were similar, and the wives they married were also the daughters of rich families, because Chen Yu was very good to Zhang Er, and since then they have become friends.
After the State of Qin destroyed the State of Wei for many years, I heard that Zhang Er and Chen Yu were former celebrities of the State of Wei, so they posted a list, offered a reward for their arrest, caught Zhang Er and got thousands of gold, Chen Yu was worth five hundred gold, the two changed their names and surnames from then on, hiding in Chen Liu yamen as errands, the funny thing is that the government appointed the two of them to follow up on this matter, they did it very seriously, it can be seen that both of them are very courageous people.
Later, Chen Sheng and Wu Guang revolted and led their troops to Chen County as a revolutionary base area, Chen Sheng wanted to claim the title of king, so he asked Zhang Er and Chen Yu if they could be called king, and the two of them replied: 'Now we should lead the troops to the west and send people to establish the descendants of the Six Kingdoms as kings, and if they are called kings, they will be the key targets of attack by the Qin army'. It can be seen that they are all very talented people.
In 207 BC, Zhang Er and Zhao Wang Xie were besieged by the Qin general Wang Li and his troops in Julu City, because of the lack of food and soldiers in the city, Zhang Er sent people to ask Chen Yu for help, but Chen Yu thought that he had few soldiers, invincible to the Qin army, and did not lead the troops to save each other, zhang Er escaped from danger, began to complain about Chen Yu, even if he explained, he could not get Zhang Er's forgiveness, and the two broke off friendship.
After the fall of the Qin state, Xiang Yu led troops into the pass, and Zhang Er was the king of Changshan, but Chen Yu was only a marquis, and he was unwilling, so he joined forces with Tian Rong, the king of Qi, to attack Zhang Er, zhang Er was invincible, and defected to Liu Bang, the king of Han, from here it can be seen that the former brothers began to kill each other.
In the second year of the Han Dynasty, Liu Bang, the king of Han, attacked the State of Chu and wanted to ask Zhao Guo for help, Chen Yu said: 'You kill Zhang Er, I will help you', once a neck-to-neck friendship, now you have to put the other party to death, this is why, jealousy, think that only by killing Zhang Er, can you restore his dignity, think that he is stronger than Zhang Er.
In the third year of Han, Zhang Er and Han Xin led the army together, defeated Chen Yu's army, and beheaded Chen Yu in Yushui, and from then on the two of them would no longer have a grudge.
But some people in history have a strong sense of brotherhood, and even if they encounter betrayal, they will understand each other.
Liu Bang and Lu Xie were brothers who played together from childhood to adulthood, and after Liu Bang became emperor, he did not forget to make Lu Xie the King of Yan, and finally although Lu Xie rebelled, his descendants were still treated kindly and were given the title of Marquis. It can be seen that Liu Bang and Lu Xie still trust each other very much, and they are not estranged by Lu Xie's betrayal.
In general, jealousy will cause hatred between brothers, and mutual distrust will eventually lead to deeper misunderstandings between brothers, so brothers should understand each other, and cannot lead to the breakdown of relationships because of a word or a thing.
