Stone carpet introduction: The stone carpet paved with stones in the manor is called the "lucky carpet". The pattern design of the stone carpet is unique and exquisitely conceived. The four corners of the stone carpet are inlaid with stone bats, and three stone coins are laid in the center. The four corners of the middle one have the word "Shou" on each corner. It means that if you step on wealth and money, you will live a long and immortal life.
