Suspended ceiling tiles (tian hua), also known as canopies (ding peng), are generally located inside the hall or room of classic buildings and serve as a component used to cover the beam structure of the roof. The construction and decoration of the ceiling panels are diverse, and there are strict rules for their use.
From a practical perspective, the ceiling tiles can embellish the interior of the buildings, making the interior look neat. They can also help prevent dust and dirt from falling from the roof to the ground. Additionally, ceiling tiles serve to keep the rooms warm in winter and cool in summer.
