Abstract: Metaverse is facing essence criticisms about falsehood in ontology and nihility in axiology. Taoism can provide defense，idea and guidelines for metaverse. In taoism， metaverse does not confuse true and false， metaverse living in the full-body immersion form is also not necessarily slide into nihility. There is no “original sins” so-called for metaverse. “Play” of free and happy in taoism can provide idea for metaverse， “satiety then play” insists on the conformity and concerns to the realistic benefits. “Leisurely play” keeps distance and transcendence from the realistic universe. “Bugan”“Buren”“Buzai”“Buzheng”， which are included in “Wuwei” in taoism， can provide practical guidelines for metaverse to avoid security， equity， freedom， and environment risks that may be brought about by metaverse technology.

Key words: metaverse; Taoism; play; Wuwei
