In China's Guangxi, Guizhou, and Yunnan provinces alone, he has personally explored more than 270 caves, and they generally have specific records of direction, height, width, and depth. It also preliminarily discussed its origin, pointing out that some caves are caused by mechanical erosion of water, and stalactites are formed by the gradual condensation of calcium-containing water droplets after evaporation.
