Introduction to strange stones: Tangyuan has collected tens of thousands of huge rocks and strange stones. After careful placement of stones by garden masters, they come in different shapes and forms; after careful maintenance by gardeners, various natural paintings appear on the stones. There are thick bushes among the boulders, and occasionally a black pine tree that has experienced vicissitudes of life appears. It looks like it breaks out of the rocks, stretches out its arms to welcome guests, or reaches into the sky. Give people shock, give people life, give people strength.
