Answer:
The story took place in the Warring States Period, mainly involved in the states of Qin and Zhao, and the main place was Zhangtai, which had a very high historical status in the Warring States period and was one of the symbols of the state of Qin. The famous Weiyang Palace was built on Zhangtai, so its significance was very special. In the story, the main characters are Lin Xiangru, the king of Zhao, the king of Qin and Lian Po, of course, the most important one is Lin Xiangru, it is his eloquence that finally allowed the state of Qin to return the bi He, which has been handed down as a good story in history, reflecting the great wisdom and courage of Lin Xiangru, of course Lian Po also had a lot of credit, while the king of Qin was reduced to a backseat. Many people know this idiom, but some people may not know its meaning. Its original meaning is that Lin Xiangru brought a flawless piece of jade from the state of Qin back to the capital of Zhao in good condition. Later, it is often used as a metaphor to return an item to its original owner in good condition, telling us that after borrowing something, we should return it instead of keeping it as our own. The return of the gem to Zhao happened in 283 years ago, at the Zhangtai of the State of Qin, and the general story is as follows: The king of Qin heard about a treasure called the He Bi, and told the king of Zhao that he hoped to exchange it with 15 cities, but the king of Zhao was worried that Qin would not fulfill its promise to give the He Bi, so Lin Xiangru offered to go to Qin as an envoy. The king of Qin gave the precious jade to his family, and then Lin Xiangru took the precious jade and stepped back a few steps closer to the pillar, wanting to crash himself and the precious jade into the pillar, the king of Qin hurriedly said that he would immediately divide the Zhao state into the city, but Lin Xiangru was still not reassured, he proposed that the king of Qin fast for 5 days and then solemnly exchange. The king of Qin had to agree, and Lin Xiangru secretly returned to the state of Zhao with the round pieces of his family.by-step explanation:
