First of all, we must know Yu Qian's famous Beijing Defence War. At that time, in order to show his martial arts, the emperor personally recruited Valle to the north, but at a stop in Tubao, Valle took the opportunity to kill the army, and the accompanying officials were robbed and beheaded, and the emperor himself was captured. At this time, Vala wanted to use military victory to break through the capital of the Ming Dynasty. At that time, ministers all said that they would move the capital, and the Ming Dynasty might be doomed. At this time, Yu Qian stood up and said that he could defend the capital. He is advancing the defenders of the capital and repelling the attack of the Walla army with weak forces. He also pointed out that the emperor's life and death were uncertain and the country could not be ruled by no one, so he proposed to establish a new monarch. Although this practice saved the country of the Ming Dynasty, it also attracted him in the future.
Later, perhaps to improve relations with the Ming Dynasty, Vara released the old emperor. Then the old emperor still had many supporters at this time, but the new emperor was ill and often could not go to court. So these people staged a coup to help the old emperor regain the throne. After the old emperor ascended the throne again, he executed Yu Qian for treason and persecuted many officials. Poor Yu Qian made great contributions to the Ming Dynasty, but died with grievances.
It can be said that Yu Qian's death was mainly due to the dissatisfaction of the old emperor, but everything he did was to save Daming Mountain. Yu Qian was later proved to be a loyal hero, and his spirit has always been respected by later generations, thinking that he is truly loyal to the country and dares to stand up in times of crisis.
