A gable-and-hip roof (xieshan ding), also known as the nine-ridge hall due to its nine roof ridges, can be classified into pointed-hipped-gable and round-hipped-gable (curved eaves) roofs. The gable-and-hip roof combines the grandeur of a hip roof with the elegance of an upturned eave, and is widely used in palaces, mansions, city towers, temples, and gardens.
