Guyang Cave is a merit cave built by Emperor Xiaowen of the Northern Wei Dynasty for his grandmother Feng Taihou. It was unearthed in the Northern Wei Dynasty, 1500 years ago. It is the earliest cave excavated in Longmen Grottoes. There are many small caves in the cave, which are exquisite and rich, and are precious materials for studying the art of grottoes in the Northern Wei Dynasty. The inscription in the cave is simple and simple in Gu Zhuo, which is a treasure to study the history of calligraphy.
In the Qing Dynasty, an emperor visited Guyang Cave via Luoyang and ordered the renovation of a Buddha statue in the cave. The main Buddha Sakyamuni was renovated into the statue of Laojun, and the cave was renamed Laojun Cave. Guyang Cave was dug in or before 493 AD. Guyangdong is located in the middle of the south section of Longmen Xishan. Since then, this place has been burning incense continuously, which continues to this day.
