Fairies can be roughly divided into three categories. The first category is seclusion after becoming an immortal; The second kind of people live in seclusion; The third kind lives in a mountainous area close to the world. The first two categories are completely isolated and self-contained. The third kind is encountered by ordinary people occasionally. According to preliminary statistics, about 1 and 20,000 people in China have become immortals since the era of the Yellow Emperor. Immortals are extremely difficult to repair, and these are all immortals after hard cultivation. However, with the long years and the evolution of the times, most of their names and touching stories are forgotten. As far as I know, the following is just a series: the first category, Xu Yuanyou of Jin Dynasty. After years of intensive cultivation in the Qing Dynasty, when he was close to becoming an immortal, he was held accountable by officials sent by the underworld. Xu mentioned the virtue of his ancestors in saving 400 people. He argued and finally persuaded the ghost collector. Xu became an immortal and went to Chicheng to live in seclusion. At that time, five members of the Xu family became immortals. The second category, for the top grade fairy, is confidential, so I won't say it. The third category, the most famous is Xu Da, the servant of Zhenjun Xu Jingyang, and his wife. When Xu Zhenjun's house skyrocketed, Xu and his wife just went out to buy rice. When they came back, they just saw the shocking scene of dozens of people from the Xu family soaring together in broad daylight. The couple were so anxious that they knelt down and begged to take them with them, but it was too late. Xu Zhenjun dropped the elixir from the air and gave it to them. After eating it, Xu and his wife became immortals and traveled between them for centuries. Also, in the Northern and Southern Dynasties, eighty members of the Zhang family revolted together, and Lu Qiong, the servant girl, stayed behind to keep the altar and become immortal.
