Everyone knows the story of "Jiang Zhiyong". Jiang Yu also heard his mother tell it. It was an old story from the time when Emperor Gaozu of the Great Chu Dynasty launched an army. It has been passed down for three generations. It is confusing and unclear. Maybe he will know it when he becomes the emperor, because it is said that the emperor is omnipotent and omniscient. This is what Jiang Yu thinks.
