There is a concubine in the harem, beautiful and beautiful, can sing and dance, and is good at, intelligent, and most favored by Zhu Di. Unexpectedly, in the eighth year of Yongle (1410), Quan Shi accompanied Zhu Di to lead troops to the north and died on the way back. While Zhu Di was grieving the loss of his favored concubine, a palace maid revealed that Quan had been poisoned with arsenic by Concubine Lu in collusion with eunuchs and silversmiths. Zhu Di was furious, and immediately ordered the eunuchs and silversmiths who had been poisoned to be executed, and Lü was tortured and burned to death with a soldering iron. Hundreds of people were killed as a result of Lu's involvement.
In the eighteenth year of Yongle, Zhu Di was preparing to be made empress's favorite concubine Wang Shi died violently, and at this time, someone in the palace reported Jia Lu, Yu Shi and the eunuch for "adultery". Zhu Di was furious. Jia Lu and Yu Shi were afraid of disaster and hanged themselves. Zhu Di did not give up, and he used the method of Zhu Lian to arrest the palace maids who were close to Jia Lu. The palace maids were tortured and falsely accused that someone in the harem wanted to murder the emperor. This confession aroused Zhu Di's murderous nature. There were nearly 3,000 palace maids involved in their own "conspiracy".
Zhu Di ordered all these palace maids to be executed, that is, Ling Chi to death.

At the time of the execution, Zhu Di personally went to prison, and even personally killed the palace maid. Zhu Di also ordered the painter to draw a picture of Jia Lu and the eunuch embracing each other, showing the inner palace and humiliating the innocent palace maidens.
