Liu prefers to categorize natural history into two levels: primary and secondary. The primary level encompasses the active involvement of the public in observing and documenting nature, as well as the practical application of the knowledge, which holds significant importance. Meanwhile, the secondary level, conducted mainly by scholars, pertains to the examination of how individuals observe nature and the progress of natural history in both China and abroad.

Chinese Journal of Natural History, edited by Liu and published by The Commercial Press, has already released its seventh issue. This series effectively integrates content from both the introductory and advanced levels, serving as a repository of cutting-edge knowledge in the field of natural history and primary level insights. The 6th Natural History Culture Forum, held in August in Sichuan province, was chaired by Liu and has garnered significant attention this summer.

When discussing the role of knowledge, Liu emphasizes that it should be a tool for serving people: "It is not important how much knowledge we possess, but rather how this knowledge can enhance our daily lives."

He encourages people to live as naturalists. He believes that, by observing the world with curiosity, approaching it with an open mind, and maintaining a naturalistic attitude, we can truly connect with our surroundings. "If we strive to live each day in the naturalists' manner, we will discover a deeper relationship with the world and, as a result, our lives will become more meaningful", says Liu.
