Taoism is the carrier of China culture, so does the decline of Taoism now mean the gradual decline of China traditional culture?

Taoism is not as great as the carrier of China culture you mentioned in your question.

Taoism is the only indigenous religion in China. Taoism probably originated in the early Eastern Han Dynasty, respecting Laozi as the ancestor. Advocate inaction, cultivate one's morality, avoid the world and cultivate immortality. Because these Taoist ideas met the needs of the rulers in some specific periods, they were supported by the rulers. But from the public point of view, some concepts of Taoism are not very attractive. Therefore, from a historical point of view, Taoist believers have always been inferior to foreign Buddhism.

At the same time, because Taoism pays attention to cultivating immortality, with the development of the times and science and technology, people don't believe this one more and more. Naturally, Taoism gradually declined.

However, its decline does not mean the decline of China's traditional culture.
