Guest-Greeting Pine:
       This is a hospitable pine tree with a tree age of over 600 years. It has tangled roots, lush branches, and vigorous branches like open arms, symbolizing the warm welcome of millions of Macheng people to friends who have come from afar. There is an old saying in Macheng: "Touch it, it's over a hundred", which shows that it is a symbol of longevity and health. It is said that this lesson was planted by Ming Taizu Zhu Yuanzhang himself.
