Emperor Zhaoyuan Yang Yuan wanted to connect the rivers from the south to the north on the grounds that Yuanhe Pond could protect people's livelihood and welfare, but in fact it was to transport gold bricks.
Taxation and corvee were heavy, and the people complained endlessly.
Yang Yuan wanted to ask Xu Chongze, the teacher of the late emperor, to come out and preside over the ceremony to show his orthodoxy. Xu Chongze was unwilling and committed suicide to apologize.
Liu Hexia, a closed disciple of Xu Chongze, presented himself to the palace with his master's relics in hand. The emperor was overjoyed, and in order to keep him by his side, he married his uncle Cui Zhi.
After Liu Hexia entered Cui Mansion, he used Cui Zhi's name to go in and out of the library, visited the ladies of the aristocratic family, followed the instructions and made a prescription and presented it to the emperor, saying it could relieve the world's sorrow. The emperor and Liu Hexia had known each other since they were children. At that time, she was a little girl who laughed heartily at the sight of a piece of candy. She didn't mind it and drank it all in one gulp.
After taking the medicine for three years, Yang Yuan gradually had uncontrollable headaches, and the imperial doctor was helpless. Liu Hexia then showed the prescription - "Gansui only, Pinellia ternata only." Yang Yuan was furious when he saw the prescription. Liu and Xia gave it licorice and said, "This is the antidote."
Liu Hexia was imprisoned for his crimes. Cui Zhi knelt in front of the emperor and begged in every possible way. He knelt in front of the prison again and expressed his hatred for Liu Hexia.
Liu and Xia never uttered a word.
Gansui is Chongze and Hegu is Pinellia ternata. The solution is difficult to find.
Mission: He who wins the hearts of the people wins the world
