In order to photograph the ancient banyan tree in thick fog, we specially set off at 4 o'clock. When we walked into the woods, the birds had just begun to chirp. The dawn light was blocked by the tall trees with widespread canopies, and the autumn breeze could be faintly felt. The birds seemed to be chirping: "Set up the tripod! Set up the tripod!" The magnificent sight of a single tree forming a forest made me feel as if I had entered some kind of magical realm. When I walked step by step from the outermost branches of a tree towards the main trunk, I took dozens of steps. Walking further inside, I could clearly see the gnarled old stems through the beams of light shining through the gaps between the branches and leaves. As I got closer, I could see the caves in the tree trunks that were as wide as a wall. Entering the cave to play felt like entering a library. There are seven tree caves in total, which are even more spacious than a two-bedroom apartment.
