The story of " Ye Lang's arrogance " can be traced back to the Warring States Period. According to the Records of the Historian, there was a small country called Ye Lang during the Warring States Period. The king of Ye Lang was arrogant and did not listen to the orders of his superiors. He even refused to pay tribute to the higher-ups. In the end, he was destroyed by the army of Chu. This incident became the source of a story that later generations ridiculed for being arrogant.
