First of all, we should know that the Queen was not crippled and blind at the beginning of her previous life, but after Zhu Qizhen was imprisoned by Mongols. At that time, the Mongols, like the Ming Dynasty, demanded money for Zhu Qizhen's life. In order to maintain the survival of Zhu Qizhen, civil and military officials at that time also collected a lot of money and gave it to the Mongols.
However, the Mongols did not send Zhu Qizhen back as they agreed, but continued to detain Zhu Qizhen. At this time, the queen spent a whole day in the temple, kneeling for a long time, praying that they could put Zhu back. After a long time, the queen's eyes began to dim, and her knees also had some problems because of her kneeling posture. In the case of poor medical conditions at that time, this situation was prone to disability, and then the queen was lame and blind.
When Zhu Qizhen came back, she saw her beloved queen, which made her even more distressed and loved her more. And in order to make the queen no longer have regrets, let the only prince also recognize her as the empress dowager. She can't have children like this, which is also a mother's dream.
Moreover, she asked to be buried with the queen after she knew that the queen could not have children and that there might be no one to worship her after her death, so that she could worship the queen for those who worshipped him. This shows that Zhu Qizhen is really a very affectionate and righteous emperor. Although the ending is somewhat tragic, I have to say that he is also a relatively tall figure among emperors.
