Thanks God those beautiful arts survived through many wars and the cultural resolution, so we still can enjoy and understand our ancients' wisdom. Thanks 樊锦诗 for the great talk.
it is a fascinating experience for us to watch your lectures on Grotto subject. even though it is your interest, still you have to sacrifice much of your time researching, authenticating , and organizing all materials to make presentations for us to enjoy. you have made us aware of the beauty of Grottos and their forgotten past. Grottos are part of human history, a history of our past culture written in stone, and a tangible record of our ancestors' vivid imagination. Through your work and dedication, you have restored the glory and forgotten part of human history. Good work and our utmost admiration. Alvin and Lily
