There is no difference, they all refer to ordinary people practicing in Taoist temples.

Taoist priests are clergy of Chinese Taoism. Male Taoist priests are called "Qiandao", also known as Zhenren, Taoist, alchemist, Huang Guan, Mr., etc., and are respectfully called Taoist priests. Women are called "Kundao", also known as female crowns.

In Taoist classics, Taoist priests call each other Taoist friends, Taoist brothers, etc. The same applies to female Taoist priests, and lay people and believers can also call them this way.

Taoist priests generally pass the tradition from master to disciple, and the disciples must receive the scriptures with gold, silver, jade, silk and other tokens. After entering the Tao, one should only focus on the Tao, observe fasts and pray, observe precepts and recite sutras, burn incense and light lamps, and do not interfere with worldly affairs.

The historical origin of the title of Taoist priests

The name Taoist priests originated from the alchemists of the Warring States, Qin and Han Dynasties, that is, those who had alchemy skills. After the founding of Taoism, Taoist priests specifically refer to Taoist clergy members who practice Taoism.

Taoist priests before and after the Sui and Tang Dynasties were customarily called Taoist priests and Huang Guan for men, and Nv Guan and Jurchen for women. Later to this day, male and female Taoists are called Qian Dao and Kun Dao respectively.

In the Southern and Northern Dynasties, the number of Taoists increased, and those who practiced at home were called "fire-resident Taoists" to distinguish them from monks.

In history, with the influence of the culture of each dynasty, Taoist priests were given relevant titles based on their level of practice and doctrinal attainments, as well as the teaching positions they held.
