Introduction to Thousand-Year-Old Trees: Liujiang Ancient Town not only has many huge Huang Ge and Maliu ancient trees growing there, but also a Huang Jue orchid that is said to be 200 years old. The old yellow orchid is tens of meters tall, with lush branches and leaves, and the fragrance of flowers. What's more surprising is that there is a strange tree in Zeng's courtyard across the wall from this yellow orchid. The tree is covered with long and thin fruits like cowpeas. No one in the local area knew its name or its origin, so we had to call it "cowpea tree".
