Liu Feng, 55, is the curator of the Fossil Exhibition Hall in Balang Miao Village in Jianhe County. He also serves as a dedicated administrator at the Miaoling National Geopark in Qiandongnan Miao and Dong Autonomous Prefecture.

Since 1990, Liu has worked with teams from the paleontological research center of Guizhou University on field scientific expeditions, helping to excavate a large number of fossils. With support from local authorities, he even transformed his home into the fossil exhibition hall, displaying the fossils collected by the research teams.

When visitors come to this village, Liu Feng always shares his knowledge of fossils. Locals affectionately call him "the grassroots expert without diploma."

In 2022, his son Liu Xingyu also joined him in his educational efforts after graduating from university, continuing the family's dedication to fossil science and public education. (Xinhua/Yang Wenbin)
