I've watched quite a few Dunhuang Grottoes videos. None of them showed the inside of Cave #96 which houses the big Maitreya Buddha statue, except yours. Taking pictures inside the caves is forbidden so I don't know how you obtained the photos of the big Buddha but good work, my man! You also told us the statue's origin and the work done to it over the centuries which i've never known before. So my sincere thanks for sharing!
