Introduction to the No. 1 Mill in the World: In the ruins of Shentong Temple, there is an oil mill with only the bottom remaining, which was used by more than a thousand monks in the temple in ancient times to grind rice and noodles. In 2001, the scenic spot restored an identical stone mill near Yingcui Bridge. The stone mill is 6 meters in diameter and weighs more than ten tons, so it is known as the "No. 1 Mill in the World".
