There is a Huabu Mountain in the northeast of Jinan, which is called Huashan for short. In the fourth year of Jin Xingding (1220), Chen Zhiyuan, a disciple of Qiu Chuji, a master of Quanzhen religion, built Huayang Palace in Shannan, which was later praised as a scenic spot in Jinan.

Huayang Palace, which is rugged and surrounded by mountains and lakes, used to be composed of 10 courtyards. It is the largest and oldest Taoist temple in Jinan. Cigarettes are dazzling all year round, and pilgrims come in an endless stream all year round. Four Seasons Hall, the main building of Huayang Palace, consists of a roll shed, a main hall and a high platform. The platform is surrounded by stones, and the center of the 13 step is paved with stones to form a deep relief of clouds. There are 3 rolling sheds, and the main hall connected as a whole is hard mountain type, with 5 rooms wide and 3 rooms deep. There are gods in spring (Ju Mang), summer (Zhu Rong), autumn (Ru Shou) and winter (Xuanming). There are dragon reliefs on the front, middle and inner columns, and black dragon claws protrude from the beams of Ming and Moon, which is daunting and chilling. There are also many plaques, couplets and murals inscribed by celebrities in past dynasties. There are two temples in the east of Four Seasons Temple, the ugly father in the west and the filial piety temple in the west. The west courtyard of Four Seasons Temple is Jingtu Temple. There are several Buddha statues in this temple. Under the Pure Earth Temple, there is the Guanyin Dizang King Hall. In the west, there are three churches. In front of them, there is Mount Tai Palace, namely the Niangniang Temple in Yuan Jun, Bi Xia. Four Seasons Temple East is the former site of the Dragon Palace, so there are ten famous doctors in the East of Sanhuang Temple. There is also a small temple in the northwest corner of the Three Emperors Hall. Out of the north gate of the Four Seasons Hall, you can climb the Jade Palace. Standing in the Jade Palace, you can have a bird's eye view of the Four Seasons Hall. Jade Palace is the Sanyuan Palace in the west, with three temples of heaven, earth and water on both sides, five underground palaces, and Guandi Temple in the southwest of Sanyuan Palace. After reconstruction, Huayang Palace officially opened to the outside world on May 1 2006.

There are dozens of towering cypresses in the Huayang Palace, which are vigorous and luxuriant, and the hall under the shade is particularly old and quiet. Walking in the meantime, it gives people an inscrutable and detached feeling. Among the ancient cypresses, there is a plant called Luofengbai, which is near the steps of the Four Seasons Temple. It is said that it was planted in the Sui Dynasty. There is also a "tea cypress" behind the Four Seasons Temple. In the past, Taoist priests used its leaves to make tea to entertain dignitaries. There are also some pomegranate trees in the temple, all of which are winding and full of vitality every spring. In the west gate, there are three stout old poplars. Although empty and dry, it is flourishing.

In ancient times, the dense forests under the mountain were mostly dense ancient apricots and old willows. As early as the Northern Qi Dynasty, Yin Xiaoyi used scenery to describe the water in the city, and the moon relied on Huashan tree poems to praise China without paying attention to ancient trees. In Wang Shizhen's place, there is also a poem called "Walking through the Magpie Hua Er Mountain". Willow flowers are full of trees, and green flowers are red. With his aesthetic vision, the painter Gao wrote in "A Moon Leaning against Huashan Tree": If you don't pay attention to China, the tree will be as bright as a comb. When the moon is at its best, onions are green.
