The difference between a Taoist and a nun is as follows: A Taoist is a female practitioner in traditional Chinese culture and is mainly found in Taoism. They usually live in Taoist temples or temples, believe in Taoism, follow Taoist teachings and precepts, and live a spiritual life with pure hearts and few desires, far away from the hustle and bustle. The practice of Daogu includes meditation, chanting, and Xi the Tao in order to pursue personal spiritual transcendence and spiritual purification. 
In contrast, nuns are female practitioners in Buddhism. They usually live in nunnery or temples, believe in Buddhism, follow Buddhist teachings and precepts, and devote themselves to Xi Dharma and seek inner peace and liberation. The practice of nuns includes chanting Buddha, sitting meditation, chanting, etc., in order to achieve personal enlightenment and the transformation of sentient beings. In appearance, Taoist gurus usually wear Taoist attire such as Taoist robes or bagua clothes, while nuns wear Buddhist attire such as monk robes or sea greens. In addition, the hairstyles and accessories of Taoist aunts are generally simpler, while nuns are more neat and elegant. 
In terms of cultural background and belief system, there are also certain differences between Taoist and nuns. Taoism focuses on personal cultivation and immortality, emphasizing respect and integration of nature and the universe, while Buddhism focuses on the equality of all beings and karma, and emphasizes the realization and transcendence of one's own heart. Although Taoist and nuns are both female practitioners, there are certain differences in beliefs, cultivation methods, and clothing. These differences reflect the rich diversity of traditional Chinese culture and religion.
