Ten-square下沉式庭院设计

Quick answer：

Sunken courtyard design is a landscape architecture style where the courtyard is lower in elevation than the surrounding ground level. It is often used in traditional Chinese gardens for creating a sense of privacy and tranquility. Design elements may include stone pathways, water features, and planting beds. The 'Ten-square' aspect might refer to a specific size or layout for the courtyard, typically around ten square meters.
