Introduction to Yongxue Ancient Well: The bluestone alleys are like twisted chessboard lines, with water wells scattered vertically and horizontally like a few chess pieces scattered on the chessboard. These wells are hexagonal in shape, and the wellheads are carved out of a single piece of bluestone. Regardless of severe cold or heat, wind or rain, the well water is clean all year round, slightly milky white, and refreshing to drink. There is a well in the center of the town. On the edge of the well, the word "Yongxue" is engraved with a divine pen. It is vigorous and powerful, and it is soul-stirring.
