Wei Dong-In 495 AD, Qiu Huicheng, the imperial clan of Wei State, began to dig Guyang Cave in Longmen Mountain. From 500 to 523, Emperor Wu and Emperor Di successively dug three large caves in the north, south and south of Binyang Cave. The construction of Shiyang Cave and Binyang Cave cost more than 800,000 people, and the Fangzi Cave and Lianhua Cave dug during the Eastern Wei Dynasty were also dug. Grottoes in the Northern Dynasties were all located in Longmen Mountain, and Guyang Cave was built for more than 50 years from the Hui Dynasty to the end of the Eastern Wei Dynasty, showing many China art forms, and the posture of the giant Buddha changed from the majestic Yungang Grottoes to the gentle and amiable Longmen Grottoes. The Buddha statue represented by the main Buddha in Binyang Middle Cave is smiling. Longmen Grottoes show more China art Buddha statues than Yungang Grottoes.
Tang grottoes-the most prosperous period is the Tang Dynasty, accounting for more than 60% of the total number of grottoes. During the reign of Wu Zetian, most of the grottoes in the Tang Dynasty were excavated, which was related to her long-term presence in Luoyang. Fengxian Temple is the most representative Tang grottoes, with two bodhisattvas 70 feet high, and Ye Jia, Ananda, King Kong and God King each 50 feet high (the length of Tang Dynasty). The scale is the first in Longmen Grottoes. It took four years, and Wu Zetian paid 20,000 yuan herself.
