The term 'Inn下沉式庭院实景' refers to the actual view of a sunken courtyard in a country inn. Sunken courtyards are a traditional architectural feature in Chinese gardens, where the courtyard is situated below ground level. This design creates a sense of privacy and seclusion, often incorporating natural elements like water, rock, and plants. In modern times, such courtyards are still popular in boutique hotels and inns for their aesthetic and tranquil ambiance.
