Introduction to Mochi Square: When Mi Fu first arrived in Dantu, he exchanged a mountain stone with a local wealthy businessman for a homestead, built Haiyue Temple under the Ganlu Temple in Beigu Mountain, and began his life in Dantu. He liked this piece of Yanshan very much and wrote a special article about Yanshan to describe his love. This handwriting of "Inscription on Mountain" spread to Japan, and the Palace Museum spent nearly 30 million yuan to redeem it from overseas and preserve it as a national cultural relic.
