What are the names of the stone carvings on many gates in Hongcun and Lucun? See the figure below)

The doors of Huizhou buildings are all equipped with gatehouses (the smaller ones are called door covers), which are mainly used to prevent rainwater from splashing on the doors along the walls. Generally, the door covers of farmers' homes are relatively simple. At a distance from the upper part of the door frame, the eaves and feet protruding outward are made of water mill bricks, covered with tiles and carved with some simple decorations. The gatehouse of the rich family is very particular, and there are many brick carvings or stone carvings. For example, on the fifth floor of the Jinshi Gate Building in Yansi Town, Huizhou District, there are three rooms and four columns, which are built in imitation of the Ming Dynasty archway and are made of bluestone. The gatehouse is carved with double lion balls, which is vivid in image, exquisite in knife work, and elegant and luxurious with huge drum stones on both sides of the column. In the gatehouse of a residential building in Yuliang Town, Shexian County, there is a brick carving "Hundred Pictures" between two horizontal purlins. Hundreds of figures carved at the screen level have different shapes, full of charm and lifelike. The gatehouse is the facade of the house and a symbol of the owner's status.
