Leshan Giant Buddha has a set of cleverly designed and concealed drainage system, which plays an important role in protecting the giant Buddha. In the18th floor of the head of the Giant Buddha, there are horizontal drainage pipes on the 4th, 9th and18th floors respectively, and a drainage pipe on the left side of the right chest is connected with the drainage pipe on the back of the right arm.
Behind the ear, near the cliff, there are caves connected left and right; There is a hole at each end of the chest and back, but they don't drill through each other. These ditches and caves form a scientific drainage, moisture-proof and ventilation system to prevent the erosive weathering of the giant Buddha.
