In fact, the black-faced flower is the normal state of Leshan Giant Buddha's face. In the past few decades, the face of the giant Buddha has been painted several times and has been pasted with 6~7 layers. The dense water vapor in Sichuan basin moistens the pores of the repair layer and becomes a paradise for microorganisms.
Leshan Giant Buddha, a world natural and cultural heritage, ended its "closed physical examination" for more than 200 days, and its face "maintained" by steam, sandpaper and lead-free cloth reappeared pink and tender. But this charm didn't last long. A few months later, black spots reappeared on the cheeks of the giant Buddha.
On the issue of protecting the giant Buddha, we should not be short-sighted, have the idea of fishing with exhausted resources, or hold the thinking of muddling along and mending seams. We should realize that the giant Buddha has fed many people in Leshan, nourished the eyes and hearts of countless tourists, and brought great economic benefits and cultural heritage value. Only by protecting the giant Buddha can we continue to maintain and enhance this benefit and value.
For example, increase the longitudinal section of the third drainage corridor, excavate to the relative water-resisting layer, and open the left and right asymmetric caves. You can also consider drilling rows of holes behind the giant Buddha, combined with horizontal corridors, to prevent the harm of water seepage in saturated zone to the giant Buddha.

Only by protecting the giant Buddha can we continue to maintain and enhance this benefit and value. Behind a giant Buddha are thousands of related practitioners and thousands of years of history and culture. Today, we have the ability and initiative to protect it. Time can't go back, and we can't wait until we lose it to regret it.
