The 6th and 12th caves, known as the "First Great Cave" and "Music Cave" of Yungang Grottoes, were officially opened on the 16th after being closed and repaired. Since its closure on November 28, 2023, Cave 6 of Yungang Grottoes has undergone over 300 days of maintenance and repair. This is the largest, most complete in design, richest in content, and intricately carved cave in Yungang Grottoes, and also one of the best preserved caves. According to statistics, there are over 2900 Buddhist statues of various types in existence in this cave, with numerous appearances and unique styles, making it the "first great cave" in Yungang. The sixth cave was completed in the 18th year of the Taihe era (494 AD) before the Northern Wei Dynasty moved to Luoyang. The cave presented a completely new appearance, with a complete sequence of Buddhist stories, unified clothing and unique architectural spatial structures, which attracted the attention and research of many scholars at home and abroad. After the closure of Cave 12 in Yungang Grottoes on November 11, 2024, digital protection work has been carried out. The four walls of Cave 12 are covered with layers of flying celestial instruments, showcasing various musical instruments from the Western Liang, Kucha, Tianzhu, and Central Plains regions at that time, with a total of 14 types and 50 pieces. It is a representative of the folk music carving in Yungang Grottoes, a temple for studying Northern Wei music and dance, and also the most comprehensive physical material for studying the history of Chinese and foreign music, hence the name "Music Cave". Meanwhile, due to the need for cave investigation and maintenance work, Cave 5 has been decided to be closed from December 16th. The specific opening date will be determined based on the progress of the work. The Yungang Grottoes are located at the foot of the Wuzhou Mountains, 16 kilometers west of Datong, Shanxi Province. They were first built during the Northern Wei Dynasty's Heping period and currently have 45 main caves, totaling over 1100 small niches and more than 59000 statues of various sizes. It is one of the largest grotto groups in China. In 2001, the Yungang Grottoes were inscribed on the UNESCO World Heritage List. (New Society)
