The description 'Courtyard with Xun Gua, built false mountain and fish pond' refers to a traditional Chinese garden design featuring the Xun Gua (Wind and Thunder) trigram from the I Ching. In this setting, a false mountain and fish pond are incorporated into the courtyard, creating a harmonious blend of natural and artificial elements. False mountains are constructed to represent the mountains in the garden and are often used to symbolize the Chinese concept of 'feng shui'. Fish ponds, on the other hand, are a popular feature in Chinese gardens, representing wealth and tranquility. The design reflects a balance between human and natural realms, aiming to create a serene and auspicious space.
