In the middle of the rain, there are many visitors to Longan Temple, which is concentrated in Shiting. Shiting does not borrow a single plant or tree, but consists of three low oil-soil walls, 15 stones and white sand. Fifteen stones are arranged in five groups: 5, 2, 3, 2 and 3, which can't be seen at once from anywhere. It is said that here 15 represents the "perfect" - "everything is not perfect, and the perfect only exists in your heart, that is "the heart of contentment". Fig. 6 and 7 are stone tea ceremonies in the form of ancient Chinese bronze coins, which use a pure hand water bowl "squatting". In the center of the squatting is a quadrangular orifice with four characters "5, Ji, Yao, Pi" engraved on the edge of the mouth, and with "mouth" as the center, four words "I only have enough" are combined. The source of water on the bowl continuously injects words of fixed size, and the excess water can only spill over. Squatting will "the heart of contentment" through the pattern flower to explain the essence of "the contented are rich and poor, the greedy are rich and poor" and Shiting has the same work.
