What are the architectural features of the "Yuanyang Hall" in "Ligengtang Panzhai"?

The Yuanyang Hall in the north of the garden is one of the few remaining nanmu halls in my country and is very precious. The Yuanyang Hall can be divided into two halves, the north and the south. One is round and the other is oblate. The two halves are called the Yuanyang Hall. The structure and decoration are all made of nanmu. Because nanmu is expensive, it is often used to highlight the identity and status of the owner.

Brick carving art is widely used in traditional architecture and is a major feature of Suzhou folk houses. Brick carving artists often reflect people's wishes for peace, luck, and tranquility through the flowers, birds, animals, and characters they sculpt.

Due to the texture of bricks, the general pattern structure is not very complex, but rigorous and full. It uses changeable forms to highlight its simple and simple style, achieving a solemn and elegant effect.
