As for when and where Xiang Yu lifted the cauldron, there was no accurate description of how heavy it was. According to the weightlifting ability of Hercules in the world now, the weightlifting ability of the strongest person in the world is about five or six hundred Jin, and the weight of some cauldrons in Qin and Han Dynasties is also roughly the same. Therefore, it is not a compliment or a mystery for Xiang Yu to hold the tripod. Theoretically, it is completely possible. According to official records, it is speculated that Xiang Yu's holding the tripod should not happen after he fought for Qin, but most likely when his uncle Xiang Liang just started fighting. At that time, Xiang Liang killed the Shouyin boy in Huiji County by stratagem, and called all the people together to fight against the State of Qin. Many people were not convinced, so Xiang Yu killed dozens of people for his uncle. At this time, he used the tripod to prove to everyone that he was invincible, and he could win everyone's trust and build confidence against Qin. Xiang Yu's tripod-holding incident is used to deter everyone, make everyone agree that Xiang Yu's divine power is invincible, and also establish prestige for Xiang's army. Lifting the tripod itself is symbolic. If no one plays tripod by himself, I believe no one will do it. The purpose of holding the tripod is nothing more than proving one's ability to the people present at that time, and making people bow to their invincible power.
You can't believe all the records in history books, and you can't believe them all, because you have no other sources of information. You can think that he lifted the tripod, because in the Warring States period, the person who could lift the tripod not only showed that a person was strong, but also showed that a person was ambitious and idealistic. What is a tripod? Jiuding in Zhou Dynasty is a symbol of the world, and Jiuding is Kyushu. With Jiuding, you can own the world, so Chu Zhuangwang always wanted to win the Central Plains, and finally gave the minister a statement that the symbol of the world was in Germany. Qin Wuwang is also holding a tripod. He could hold the tripod of the Zhou emperor, but he accepted the gift from heaven, because Qin was still a vassal state at that time and did not deserve to enjoy the world.
Why did overlord Xiang Yu carry the tripod? Because the heroes of that era want to prove themselves quickly and establish their image among the people, which is simple and direct. Xiang Yu wanted to unite others against the State of Qin, so people wanted to see if he was capable and qualified to please him, so he was tested and the result lived up to expectations. He succeeded, and he also succeeded in uniting friendly troops from all over the country, thus starting the road against Qin.
But in fact, he is holding this tripod, not the legendary one thousand catties. It is impossible for a normal human being to lift it if it is calculated by modern units of measurement. Scientifically speaking, the maximum weight that a person can lift is about 80-90 kilograms, and it is basically impossible to exceed this weight. Even if Xiang Yu is really fierce, the tripod he lifted is more than 700 kilograms in history, but this weight unit is also the Jin of Qin State, which is equivalent to 252 grams now, and 700 kilograms is also 170 kilograms. Being able to lift it also means that he is great.
