The writing background of Tang drama's mission.

"Tang Ju Live Up to the Mission" tells the story of Tang Ju's fierce face-to-face struggle with the king of Qin when he was sent to the State of Qin on the orders of An Ling Jun. Tang Ju (jū) was a courtier of An Ling. Anling is a small country belonging to Wei State. An Lingjun was originally Wei Xiangwang's younger brother. At that time, South Korea and Wei, which were close to Qin State, perished one after another, while Zhao, Yan, Qi and Chu, which were among the other six countries in Shandong, had already been separated by Qin State for years and were dying. A few years later, Qin unified the world. After the demise of its suzerain state Wei, Anling once maintained its independent status. The king of Qin wanted to take Anling lightly by deception. This is an old trick of Qin Jun, luring small fish and catching big fish to get profits. King Hui of Qin once sent Zhang Yi into Chu, giving 600 Li to the land he managed, on condition that he broke off diplomatic relations with Qi. As a result, the fool Wang Huai was taken in. Qin Xiang invited Huiwen's wife to fifteen cities. As a result, the scam was discovered by Lin Xiangru, and stealing chickens does not erode rice. These things were sent by Tang Ju, but only a few decades ago. Ying Zheng, the king of Qin, did the same thing, and Anlingjun and Tang Ju chose to fight resolutely with the tiger and the wolf.
