When Dugu Yi was not yet an official, he lived at home and had a hobby of drinking. His wife refused to buy wine, so Dugu Yi had to ask Xu Anni for wine. Anni replied, "I don't have money to buy wine." Dugu Yi said, "Why don't you ask Maogui to go to Yuegong's house to get money to buy wine?" Anni had to pray secretly. In less than an hour, the money for buying wine was delivered. Dugu Yi kept asking Anni to withdraw money from Maogui to buy wine.

After Dugu Yi became an official due to internal ties, one day he said to Xu Anni in the garden: You asked Maogui to Queen Dugu (Dugu Yi's half-sister) and said, "My family has no money, please give me money often." Anni prayed to Maogui as he said, and Maogui really walked to the Sui Palace and took goods from Queen Dugu.

Once, Xu Anni arranged a table in an empty room in the palace, and placed a pot of fragrant porridge and a spoon on the table. He beat the porridge with a spoon and said, "Miss Cat, come and eat porridge. But you can't live in the palace." She kowtowed and prayed, muttering words. Not long after, her face turned pale, and her limbs seemed to be holding her, and said, "The cat ghost is here."

This incident was written by someone to Emperor Wen of Sui (5604 AD). Emperor Wen said: This is a kind of monster and ordered Xu Anni to be driven away. Soon Dugu Yi was sentenced to death. His younger brother begged Emperor Wen and was dismissed from being a commoner. The cat ghost also disappeared (see the biography of Dugu Yi in the Sui book)

The people's guises are often spread to the court in criminal cases. In the eighth year of Qingli (1048 AD), Renzong looked through Fu (province) and reported to the court's criminal cases one day. People often vented guises to harm people. Renzong was very sad. Another time in criminal cases. There was a doctor named Lin Shiyuan in Fuzhou who used Chinese medicine to treat gui poison, which was very effective. Renzong told his recent officials: Lin Shiyuan's prescription for treating gui can be handed over to the imperial physicians in the palace for review. Together with the secret recipes for treating gui collected by the imperial physicians, they were collected into a collection, printed into a special book, issued various ways, and transferred to the people in various places for use (see the 49th volume of Zizhi Tongjian).

The Song Dynasty was very strict in the management of people who had a criminal record of raising gu and raising gu. In the second year of Taizu Gande, he ordered the 326 families of people who raised gu in Yongzhou (Lingling County, Hunan Province) to be moved to local remote areas, and they were not allowed to enter the city (same as the book, Volume 4).

In addition to different types of Gu, there is also a certain period. People who are involved in Gu will commit the Gu poison at a certain period. After the Gu poison is executed, there is an antidote to be relieved. If a certain period is passed, there is no cure to save it. During the orthodox period of Emperor Yingzong of the Ming Dynasty (14361449 AD), Zhou Li, a businessman from Wujiang County, Jiangsu Province, worked abroad since childhood. One year, he went to Sien Mansion in Guangxi Province and accidentally met a middle-aged widow named Chen. After the matchmaker said that Zhou Li agreed to marry into the Chen family as a husband. Since then, he has settled in the local area and gave birth to a son soon. Time flies, and more than 20 years old, and his son is also sixteen years old.

After middle age, when people think of what happened when they were young, they would have the idea of ​​falling leaves returning to their roots. His wife couldn't stop it, so she had to let him go and asked his son to go back to his hometown in Wujiang with his father. Chen released a Gu for Zhou Li and secretly told his son: Your father was willing to come back, so he would relieve the Gu for him. Zhou Li and his son returned to his hometown in Wujiang. In less than a year, Zhou Li's Gu made a bucket of water every day, and his stomach was as big as a bucket of water. His son said to his father: Dad! Let's go back to Guangxi! I miss your mother too, but I have this strange disease and can't walk! Dad, I can treat your disease. You are not a doctor, how can you cure the disease? His son treated his father's Gu according to the method his mother taught him. Zhou Li vomited a live crucian carp in his stomach, and this crucian carp was the Gu his wife gave him.

J. Xing County, Xi Province had a criminal case against Gu during the Daoguang period of the Qing Dynasty (1821, 1850 AD). A newly moved guest Zhao Ruzhan was accused by villagers Zeng Qizhou and five others of making a victim. The process of this case was as follows: Zhao Ruzhan moved from Changting, Fujian to Xingguo County, Jiangxi Province, and opened an oil shop for sole proprietorship. He hired workers Zeng Qizhou and five others of oil, and in addition to paying wages, they also provided lunch. Zeng Qizhou and five others of five others of work after lunch. After eating at noon on the first day of work, they felt stomach. Zi was in pain and immediately went home to hire a doctor for treatment. The doctor thought they had ordinary abdominal pain and prescribed prescriptions and took medicine. Their stomach was still hurting and their bodies were losing weight day by day. Three other passersby passed by Zhao's store and bought peaches from his store. Their stomach also hurt after eating them. Zeng Qizhou had money dealing with Wu Laoliu, a servant in Zhao's store. Wu Laoliu went to Zeng's house to ask him for the borrowed money. Zeng Qizhou said to Wu Laoliu: Take mine.

If my disease is cured, I will return the money I borrowed to you. If my disease cannot be cured or even dies, no one will pay back your money. Your disease is Yang Laoliu. Yang Laoliu was brought by the boss (referring to Zhao Ruzhan) from Changting. He has an antidote that can cure your disease. In order to get back the loan, Wu Laoliu told Zeng Qizhou the secret. He asked Wu Laoliu to ask Yang Laoliu to give medicine to treat the disease and give him some money. Yang Laoliu had to secretly give the antidote Leave it to Wu Laoliu, Zeng Qizhou Wu took the medicine, and it was not long before the poison that was released from the stool. The poison that was released was half an inch long, white, the mouth of the gu was like a needle, and the color was blue. Zeng Qizhou's illness turned a little and could not wait to accuse Zhao Ruzhan of the main hall of Xingguo County to release the poison that harmed people. The matter was made public. The local doctor Chen Xiqing also cured the poison that Zeng Qizhou and eight others, and the poison that was removed from the stool.

After the truth of the case of the release of the Gu, Wu Laoliu and Yang Laoliu also revealed that the Gu raised by Zhao Ruzhan had three types, including melon, snake, and insect. The Gu is a melon insect, which is shaped like a melon and is as big as a date. The snake insect is shaped like a snake. The insect insect is smaller than a snake and has a large number. The poison among the eight people including Zeng Qizhou was the insect insect raised by the Zhao family, which was caused by a kind of grass chicken ridge firewood collected from aquatic plants.
