Ms. Zhao Jing from Elephant Travel Agency gave a wonderful presentation. The Longmen Grottoes, situated on both banks of the Yi River in Luoyang, are a World Heritage Site. From the Northern Wei to the Sui and Tang dynasties, artisans spent centuries carving thousands of statues into the cliff face. The Vairocana Buddha, dignified and graceful, perfectly embodies the grandeur of the Tang Dynasty. The Yi River flows gently, the Buddha niches stand serenely, and the stone carvings are delicate and vivid. They represent the pinnacle of ancient stone carving art and are a thousand-year-old history book etched on the cliff face. A stroll through them is truly awe-inspiring.
