Chengkan village in Huizhou District is famous for the residential architecture of the Ming and Qing style. Baolun Hall in the Ancestral Temple of Luo's, built during the Jiaqing's reign in Qing Dynasty, is a representative collection of typical Huizhou architecture. The temple covers an area 5 mu (1/3 hectare). Baolun Hall was well designed and constructed with extreme delicacy. Through the first entrance, visitors reach "Tianjing" - a square dooryard with rooms on each side designed for enough lighting and draught. Then come to a great hall, in which four vermilion posts support the timber frame. Further across a yard is the main hall - Baolun Hall. The design of this timber frame hall is delicacy and unique. Exquisite engravings of flowers and geometric pattern on the bluestone parapets and creative colored paintings on the beams, lintels and doorframe lure many foreign visitors. The colors remain bright and fresh although throughout ages. A pair of wooden staircases ascends to the second floor on which though the finely engraved casements, visitors can have a perspective of the Huangshan Mountains.
