According to The Story of Guang Yi written in the Tang Dynasty, Liu Huafei became a ghost and had a dream for her son Li Cong, telling him that her grave had been destroyed. This statement is a bit bizarre and absurd, so later generations think that Li knows this because he has a heart-to-heart mother-child relationship with Liu Huafei.

Liu Huafei is the concubine of Emperor Xuanzong of the Tang Dynasty. When it comes to concubines of Emperor Xuanzong of the Tang Dynasty, many people will first think of Yang Guifei, and then make up the romantic drama that the emperor only loves. But in fact, Xuanzong of Tang Dynasty is very romantic. Besides Yang Guifei, other concubines are also very popular with him, and Liu Huafei is one of them.

And Liu Huafei has an advantage over Yang Guifei. The first advantage is that he has been with Li Longji for a long time. As early as Li Longji had not proclaimed himself, Liu Huafei had already entered his home. The second advantage is that there are three sons, namely Li Yan, Li Wan and Li Yan. No matter how favored Yang Guifei is, she still has no children. In the harem, having children is also a status symbol. It can be seen that although Liu Huafei's reputation is not as good as Yang Guifei's, her actual status is still quite high.

Because of this, when she was buried after her death, Tang Xuanzong was willing to give her a lot of funerary objects. However, the rich funerary objects also attracted the covet of criminals, such as grave robbers.

Although Emperor Xuanzong of the Tang Dynasty arranged many guards beside Liu Huafei's tomb, the desire for treasure led grave robbers to take risks. In order to avoid the eyes of the patrol, the grave robbers lied that someone in their family had died, so they went to the wild to dig graves, be buried with a group of people, and have funeral offerings. They first found a clearing, dug a grave on it, and then secretly dug a tunnel under the grave that could lead to Liu Huafei's grave. During the day, they pretended to hold a funeral, and at night, they began to secretly dig tunnels. Finally, they dug a passage through Liu Huafei's grave.

There are rules in the grave robbery world, you can't be greedy and take more, and you can't insult the dead. However, the mind of these grave robbers is very low. They not only stole a lot of treasures, but also cut off Liu Huafei's hands and feet to seize her bracelets and other things. They were afraid that Liu Huafei would tell them in her dream and even cut off her tongue.

Filled with resentment, Liu Huafei dreamed a dream for her eldest son, Li Cong, and told him what had happened to her. Li Cong, the dutiful son, immediately told Tang Xuanzong about it. So Tang Xuanzong sent officers and men to check the people coming and going, relying on what? Stolen goods, and finally won the lawless grave robbers.
