In the scenic area, Ruiyun (Auspicious Cloud) Temple was built in the Tongnian Region of the Daliang Dynasty (about 535 AD), formerly known as Tengyun (Climbing up to the cloud) Temple. During the years when competitions between Chu and Han was server, Liu Bang once hid in Emperor Hidden Cave, his wife, later Empress Lv, was looking for her husband. She looked into the mountains afar and found the mountain top was shrouded by auspicious clouds. She then went up and found Liu Bang. In Records of the Grand Historian-Annals of Gaozu, Empress Lv said, "the place where Ji (Liu Bang's style name) resided often emerged auspicious clouds, so I went there for look for him and I can always find him without doubt." According to this historical records, during the Reign of Huanhong, in the Song Dynasty, the temple was renames as Ruiyun Temple.

The wingceltis is the most rare and old trees in Huangcangyu. Mother Nature has created grotesque pteroceltis with twisted roots and gnarled branches. In the mountain valley and around the temples, old pteroceltis trees are growing together, some of them are upright and vigorous and others are humpback and weighed down with age. Some ancient pteroceltis have mottled barks and dry-shaped bump with branches towering high into the sky, but root deeply into the crevices, knotted due to the weather-beaten years.

The ancient tree blots out the sky and covers the sun with luxuriant foliage. It is vividly described as "an old man with his son and grandchild". To the right, there is an ancient pine with strong branches. The tress is nearly 20 meters high whose age is similar to the ginkgo.
There is also a boxwood, aged about 1500 years-It is said that the thousand year-old boxwood is very rare. According to a legend, 2,500 years ago, Confucius went about drumming up support for his idea and lecturing here.
