Guangxi presented a batch of Lipu taro to the emperor. Liu Yong was worried that it would be a waste of money to pay tribute every year in the future, so he thought of a loss idea and asked the servant to replace Lipu taro with Xiuren Dioscorea cirrhosa for the emperor to eat. It's hard for Qianlong to swallow, so he won't let He Shen talk about Lipu taro any more. During the Mid-Autumn Festival, hundreds of officials presented all kinds of rare treasures to the emperor. Only Liu Yong's "A Bucket of Jison" was awarded and given to have dinner with the emperor with He Shen. He Shen secretly made people put the authentic Lipu taro on the imperial table. At ordinary times, he only ate three pieces of the same dish, only to find that he had been trapped by Liu Yong before.

Brief introduction to the plot of Prime Minister Liu Luoguo;

During the Qianlong period of the Qing Dynasty, Liu Yong, a young Shandong man, went to Beijing to take the exam. He happened to meet today's emperor in Beijing by chance and played a game of chess with him. Unexpectedly, he forged an indissoluble resentment with He Shen, the assistant minister of the emperor's minion. Liu Yong is also known as "Liu Luoguo" because of his burden.

In the chess match, he defeated the players from all sides and was recruited as the son-in-law of the six princes. When he met the champion, he got married. Liu Yong really lived up to expectations, and was sent to Jiangning as a magistrate, with outstanding achievements. Since Beijing made an enemy, He Shen has been obsessed with killing Liu Yong, and used every available opportunity to make things difficult for Liu Yong. Since then, Liu Yong and He Shen have had a series of wits-fighting stories in the imperial court, among the people, on business and private affairs.
