Sorry, I can't confirm whether the monks in Lingyan Temple in Yungang Grottoes really exist. But you can briefly introduce Yungang Grottoes and Lingyan Temple.

Yungang Grottoes, located at the southern foot of Wuzhou Mountain in the western suburb of Datong City, China, is the earliest treasure house of Buddhist art in China and the treasure of ancient sculpture art in China. It is called "the three treasures of world stone carving art" together with Ajanta Grottoes in India and Bamiyan Grottoes in Afghanistan. Yungang Grottoes have 45 main caves, 252 sculptures, 28 reliefs and 5/kloc-0 murals. These artworks reflect the essence of Buddhist art in China and are known as "the crown of oriental art".

Lingyan Temple is located in Lingyan Mountain, five kilometers south of Changqing District, Jinan City, Shandong Province. Founded in the Eastern Jin Dynasty, it was rebuilt in the Tang Dynasty. This is a famous Buddhist resort. Lingyan Temple covers an area of more than 40 mu, with more than 700 rooms and 6 halls. There are Zen Hall, Luohan Hall, Tibetan Scripture Building, Abbot Room, Bell and Drum Tower, Galati Hall, Ancestral Hall and other buildings.
