Qian Liu, the founder of the Wuyue Kingdom, was a rogue when he was young. He once made a living by selling salt. Later he was recruited as a soldier, and gradually rose from a partial general to be in charge of the army of a state. In the process of eliminating Liu Hanhong, Xue Lang, Dong Chang and other forces, he occupied the land of two Zhejiang provinces. In the second year of Emperor Zhaozong's reign (902) of the Tang Dynasty, he was granted the title of King of Yue. In 904, he was granted the title of King of Wu. When Zhu Wen established Liang Dynasty, he was granted the title of King of Wuyue. Wuyue had a small territory. At its peak, it only governed the thirteen prefectures of Hangzhou, Yue, Hu, Su, Xiu, Wu, Mu, Qu, Taiwan, Wen, Chu, Ming and Fu. It also had Zhenhai, Zhendong, Zhongzhou and so on. Wu, Xuande, Wusheng, Zhangwu and other festival towns. Due to the small territory, few soldiers and insufficient strength, Wu Yue has always regarded loyalty to the Central Plains Dynasty as its main military strategy. Before the fall of the Tang Dynasty, Qian Liu was loyal to the Tang Dynasty; after Zhu Wen usurped the Tang Dynasty and established the Liang Dynasty, he was loyal to the Hou Liang Dynasty, and thus obtained the title of King of Wuyue and Marshal of the Military and Horse Capital from the Hou Liang Dynasty. After the Later Tang Dynasty destroyed Liang Dynasty, Qian Liu professed his vassal status to the Later Tang Dynasty. Not only did he get the title of King of Wuyue and Marshal of the Military and Horses of the World, but he also received the gold seal of the Jade Book to show his favor. With this, Wu Yue effectively defended the Wu Yue Kingdom from intrusions by surrounding separatist forces. At that time, Qian Liu proclaimed himself a minister to China and the DPRK, and on the other hand, he regarded himself as a small imperial court. His office was not only called the imperial court and his officials were ministers, but he also established his own reign title. There were three reign titles, including Tianbao, Baoda, and Baozheng, until After his son Qian Yuanguan succeeded to the throne, he changed to the Chinese reign title. At the same time, he also communicated with Silla, Bohai and other countries on his own, and created titles and titles for them, just like the emperor of China and North Korea. Despite this, Qian Liu was diligent in political affairs and understood the sufferings of the people, such as building and defending seawalls and other water conservancy projects, which won the hearts of the people. In 1932, Qian Liu passed away at the age of eighty-one. His son Yuan Guan was the heir, and his diligence was still the same as his father's. In 941 AD, Yuan Guan died, and his sons Hongzuo and Hongju succeeded him. In 947, Wu Yue's general Hu Jinsi deposed his lord Li and succeeded him to the throne with his lord's younger brother Qian Hongchu. In 1978, Qian Chu (because he avoided the taboo of the Song Dynasty, removed the word "Hong" from Hong Chu) was published in the Song Dynasty, and Wu Yue died. Counting from the time Qian Liu became the envoy of Zhenhai in 893 AD, it lasted for 86 years until its demise.
