Introduction to Rhododendron: Southwest China is the largest origin of Rhododendron in the world, and "Hua Wu Ren Jian" is the most concentrated display site of Rhododendron in Sichuan. Here we have the world's only self-cultivated azalea vases, rhododendron fences, single-pole rhododendrons, and high-pole rhododendrons. Among them, the tallest high-pole cuckoo, with a height of 4.79 meters, won the "Guinness World Record".
