What are the names of the classics that Taoist priests read during their practice, and what books do they belong to?

Of course this is the Tao Jing! Different scientific instruments (you can understand it as "rites") correspond to different Confucian classics, and I recommend thirteen most important Taoist classics to you, that is, representative Confucian classics: Moral Classic, South China Classic, Xu Chongzhen Classic, Zhouyi Shentongqi, Bao Puzi's Inner Chapter, Lao Xiangzi Jules, Lao Zi Zhongjing and Lao Xiangzi Jules.
