Introduction to the three halls of the Putuoyu Ding Dong Tomb: The Putuo Valley Ding Dong Tomb is the mausoleum of the Empress Dowager Cixi. The Long'en Hall and the east and west side halls are made of exquisite materials, fine workmanship and luxurious decoration. The wooden frame is all made of precious huanghuali wood. Liang Fang's color paintings do not use ground paint, and there is not enough pigment, but directly apply powder and gold on the wooden parts. The patterns are the highest-grade gold dragon and seal color paintings. The walls inside the hall are engraved with brick patterns that mean "long life and long life", and are all swept with red gold. The 64 exposed pillars in the three halls are all surrounded by semi-three-dimensional gold-plated copper dragons.
