Why did ancient troops break bowls when drinking before the war?

In many TV clips, we often see such a scene: an army or a group of people drink the wine in a bowl together before leaving, and then drop the bowl on the ground. In the ancient army, in order to keep the vigilance of the army, drinking was generally prohibited. If the troops are allowed to drink, there are only a few situations, one is to celebrate the victory, the other is to celebrate the victory, and the third is to treat the guests with wine. Drinking before the troops go out to war can be called strong liquor, but why do you break the bowl after drinking it? In order to understand this problem, let's take a look at the earliest origin of drinking and smashing bowls. At the end of the Warring States period, the State of Qin killed 400,000 people of Zhao in the battle of Changping, and Zhao's strength was greatly reduced, and the country almost perished. In order to avoid the demise of Zhao, Qin Jun attacked Yan and found a strong man, Jing Ke, to assassinate Ying Zheng, the king of Qin. Jing Ke went to Xiao, and the prince came to do heroic deeds. Jing Ke took the wine in the hands of the prince, gulped it down, and then threw the bowl on the ground, indicating that there was no return to this trip, or he would die if he didn't succeed. After crossing the Xiao River, Jing Ke sang loudly: The wind blows and the cold blows, and the strong men are gone forever. This bleak and tragic scene is really touching. Later, drinking and throwing bowls spread widely, usually before the troops carried out difficult tasks, or before some organizations gathered for an uprising. Bowl is not only a tool for drinking, but also a tool for eating. Breaking the bowl before leaving implies that the bowl here will not be used in the future. This action will be a desperate action, an action of risking one's life and forgetting one's death, and an action of success or failure. Throwing bowls collectively can also create a momentum, which can stimulate people's desire to win, thus improving their combat effectiveness. In addition, China's culture is extensive and profound, and many words are homophonic. Broken bowls are homophonic, and many people will homophonic for broken bowls. From this perspective, breaking the bowl is also expected to be a reward for success and safety.
