Before Liu Bang died, he arranged a loyal minister to protect Liu Ruyi and Liu Heng.

The most famous is Zhou Chang.

According to historical records, Zhou Chang was from Pei County, and he and his cousin Zhou Ke both served as the history of Surabaya in the Qin Dynasty. Emperor gaozu rose up in Pei county and defeated the county magistrate and county supervisor of Surabaya. In this way, Zhou Chang and Zhou Ke followed Pei Gong with the qualification of Deadpool history. Pei Gong ordered Zhou Chang to be the flag bearer, and Zhou Ke made a guest appearance under the account for the time being. Later, they all followed Pei Gong into the customs and overthrew the rule of Qiang Qin. Pei Gong was appointed as Hanwang, and Hanwang appointed Zhou Ke as suggestion and Zhou Chang as lieutenant. In the fourth year of Hanwang (the first 203 years), the Chu army surrounded Hanwang in Xingyang, and the situation was urgent. Hanwang quietly escaped from the encirclement and ordered Zhou Ke to stay in Xingyang City. The Chu army attacked Xingyang and wanted to appoint him as a general. Zhou Ke thundered: "You people should surrender to Hanwang as soon as possible, or you will be captured soon!" Xiang Yu was furious and immediately cooked and killed Zhou Ke. Therefore, Hanwang worshipped Zhou Chang as an ancient counselor. Always follow Hanwang and defeat Xiang many times. Thus, in the sixth year of Emperor Gaozu (20 1), Zhou Chang was blocked together with Xiao He and Cao Can, and Zhou Chang was blocked as the marquis of Yin. Zhou Gen, his son, was also named Gao because his father died for his country. Zhou Chang is patient and strong, and dares to speak out. Since Xiao He, Cao Can and others have been in awe of Zhou Chang. On one occasion, when Gaudi was resting, Zhou Chang went to the palace to play. Gaudi hugged Miracle. When Zhou Chang saw this scene, he ran back. After catching up, Gaudi rode on Zhou Chang's neck and asked, "What emperor do you think I am?" Zhou Chang straightened his neck and looked up and said, "Your Majesty, you are the same emperor as Xia Jie and Shang Zhou." Gaudi smiled, but he was most afraid of Zhou Chang. When Emperor Gaudi wanted to abolish the Prince and let Miracle's son be the Prince, many ministers resolutely opposed it, but it didn't succeed. Later, fortunately, Sean made a plan for Lv Hou, which made Gaudi put it aside for the time being. Zhou Chang argued with the emperor in the palace, and Gaudi asked him why, because Zhou Chang had a stuttering problem, and even when he was very angry, he stuttered even more. He said, "Although my eloquence is not very good, I ... know that this is impossible. Your majesty, although you want to abolish the prince, I will definitely not accept your imperial edict. " Gaudi listened and smiled happily. After the incident, Lv Hou listened to the above conversation in the East Room. When she saw Zhou Chang, she knelt down and said, "If you didn't argue, the prince was almost abolished." Since then, Miracle's son Ruyi was named Wang Zhao at the age of ten. Gaozu was worried that Wang Zhao would be killed if he died. At that time, there was a man named Zhao Yao. He was very young. His official position is an imperial adviser in charge of the government. Fang and Gong of Zhao said to each other, "Although your prime minister is young, he is a wizard. You must treat him differently. He will take your place in the future. " Zhou Chang said with a smile, "Zhao Yao is young, but he is just a small official with a knife and a pen. How can this be! " Soon after, Zhao Yao went to serve Gaozu. One day, Gaozu was alone and unhappy, and he lamented generously. Manchu civil and military officials don't know why the emperor did this. Zhao Yao stepped forward and asked, "Your Majesty, is it because the Prince of Zhao is young and Lady Qi is at odds?" ? Are you worried that Prince Zhao Can will not be able to save himself after you live forever? "Gaozu said," Yes. I am very worried about this privately, but there is nothing I can do. " Zhao Yao said: "You'd better send a noble and powerful prime minister to Wang Zhao, and this person must be the talent that Lv Hou, the prince and his ministers are afraid of." Gaozu said: "Yes. I think this is what I want to do, but who can shoulder this heavy responsibility? Zhao Yao said: "Zhou Chang, an ancient historian, is a person with strong honesty and frankness. Besides, everyone from Prince Lv Hou to the civil servants of the Manchu government was in awe of him. Therefore, only he can shoulder this heavy responsibility. " High-impedance said, "good. So Gaozu summoned Zhou Chang and said to him, "I think I must trouble you. You should help Wang Zhao for me. You should be his prime minister. " Zhou Chang cried and replied, "I followed your majesty from the beginning. Why did you throw me to the vassal king on the way? Gaozu said: "I know this is a demotion, but I am really worried about Wang Zhao in private. After careful consideration, no one can do it except you. If you really have to, just go! " So the suggestion doctor was transferred to Zhao. After the death of Emperor Gaozu of Han Dynasty, Lv Hou sent messengers to summon the Prince of Zhao to the palace. The Prime Minister told the Prince of Zhao that he was in poor health and could not go. The emissary went back and forth three times, but Zhou Chang insisted on not sending the prince of Zhao back to Beijing. So Lv Hou was very worried, so he sent messengers to call Zhou Chang to Beijing. After Zhou Chang went to Beijing, he met Lv Hou. Lv Hou scolded him angrily: "Don't you know that I hate Mrs Qi very much? You won't let Wang Zhao go to Beijing. Why? " After Zhou Chang was called into Beijing, Lv Hou sent messengers to call the Prince of Zhao. Soon, the prince of Zhao really came to the capital. He went to Chang 'an for more than a month and was forced to drink poison and die. Therefore, Zhou Chang resigned due to illness and no longer went to the court to visit the Queen Mother. Three years later, he also died.
