[Pattern] Today, light rain and snow, to the school (now located in Suining County Liangji Qiji Village) light rain always makes people think: the historical Qi Ji (BC.224-BC.194) called Qi Ji, the Western Han JinLing (now Suining County, Xuzhou City, Jiangsu Province, Liangji Town, Qi Ji Village), Han Gaozu Liu Bang favored Qi Ji. When Liu Bang was the King of Han, he married Liang Ji Qi Ji and was very pampered, and Qi Ji gave birth to Liu Ruyi. Liu Bang gave both the real estate deed and the bank card to Qi Ji (the peak of Qi Ji's life), because the crown prince Liu Ying was benevolent and cowardly, Gao Zu thought that he was not like himself, and often planned to abolish the prince and establish Ruyi, and often said "Ruyi is like me". Qi Ji often accompanied the emperor on expeditions to the Kanto region, weeping day and night, hoping to make her son crown prince. Lü Yan, on the other hand, was older, often stayed in Guanzhong, rarely saw the emperor, and became more and more estranged. Ruyi was given the title of King of Zhao, stayed in Chang'an, and was almost made crown prince several times. Fortunately, the chancellor vigorously opposed it, and when his uncle Sun Tong entered the court, Lü Hou adopted the strategy of staying with the marquis, and did not replace the crown prince. Poor Qi Ji was finally too small to take over the plate because the pattern was too small to finally become a man who killed his son Liu Ruyi, the King of Zhao, and was poisoned by Lü Hou, which was a pity!
