What does "Purple House" mean?

"Purple House" is called the place where immortals live in Taoism.

Zifu is the office of Donghua Dijun School. During the Qin and Han dynasties, it was said that there were three islands in the sea, and ten continents were among them: Shangdao, Penglai, Abbot and Yingzhou; The three islands in Zhongdao are Meirong, Yuen Long and Yaochi; The three states of Xiadao are Chicheng, Xuanguan and Taoyuan. Three islands and nine continents stand in the middle of HarmonyOS. Between the three islands, there is Zifu County, which is the official position of Emperor Donghua, competing with the immortals, from the ground to the immortals, from the immortals to the immortals, from the immortals to the immortals, from the immortals to the true saints, and into the land where there is nothing. These three moves are all managed by Donghua the Great. According to the first explanation in the Complete Works of Three Professors, "Donghua people were born from the true spirit of Emperor Donghua, and they divided and ruled the East Pole, ranking above Donghua. Zifu, who lives in Zifu and is in charge of the 354th Division, moved to the Cave of Heaven and Virtual Palace, which is better than the real fairy. Yang is the proprietor, Shaoyang is biochemical. The emperor is the respect of the eastern heavens, and the monarch is the master of living things. " And respectfully called "Donghua Zifu Shaoyang Emperor"

We can also find many similar works from the collection, such as puppet show, wandering immortals, drinking, and the first poem "Dianjiang Lip". They all depict a magical fairy tale world above space. There is the "purple mansion" that Taoism often says. There are golden beds and jewels hanging in the purple mansion. There are magnificent caves, and strange incense and different fires burn everywhere. The flat peaches in Yaochi are ripe for thousands of years.
