When did the strike start?

In 279 BC, in the name of enhancing the friendship between the two countries, the King of Qin sent an envoy to meet the King of Zhao in Mianchi (now Mianchi County, Henan Province). In fact, he wanted to blackmail the prince of Zhao, who knew that the king of Qin was fragile and worried about a plot against Qin, so he didn't go. However, Lin Xiangru, the counselor, and Lian Po, the general, thought twice, and advocated that the prince of Zhao should go to the meeting. If he didn't go, Qin laughed at him and killed himself. The prince of Zhao thought that the two ministers were right, and decided to meet the king of Qin at Mianchi, and ordered Lin Xiangru to accompany him. General Lian Po arranged heavy troops at the border to prevent accidents. At the banquet, the king of Qin was full of domineering, pretending to be drunk and teasing the king of Zhao by innuendo, saying, "I heard that the king of Zhao is good at playing the harp, and I want to invite him to play a song today to entertain me." The prince of Zhao dared not disobey and managed to play a song. Unexpectedly, the prince of Zhao was trapped, and Qin historians quickly recorded it: on a certain day of a certain month, the king of Qin ordered the king of Zhao to play drums. Lin Xiangru was very angry when he saw this. He walked up to the king of Qin and said, "The king of Zhao heard that the king of Qin was good at fighting, and he won today's meeting. He also asked the king to beat him. " The king of Qin refused, with a firm refusal. Lin Xiangru asked again, "If your majesty doesn't obey, I'm willing to spill blood from my neck on your majesty within these five steps." The king of Qin immediately drew his sword to kill Lin Xiangru. Lin Xiangru deadpan, loudly reprimanded, the crowd was dumbfounded with fear, and the air was extremely tense. In order to alleviate the immediate crisis, the king of Qin had to knock a few hammers. Lin Xiangru immediately ordered the Zhao Historian to write down: On a certain day, a certain month, a certain year, the king of Qin attacked the king of Zhao.

The jar struck by the king of Qin here is the jar in the word kiln, which is the pottery used to hold wine in ancient times. It was used as a musical instrument in the Spring and Autumn Period and the Warring States Period. Chinese characters are hieroglyphics at the earliest, and the formation of the structure of "kiln" has a certain foundation. This leads to our research from a certain aspect. The most primitive cave dwelling is to use ready-made caves, or dig caves, build them with stones, and fire pottery such as "utensils" in them. Until the later Dragon Kilns, Ban Kilns, and even today's inverted flame kilns and tunnel kilns, there was a "cave", which was a firing chamber for firing various products and was made of various refractory materials. The products fired inside are not ancient and simple, but all kinds of exquisite ceramic products.
