When I first arrived in Kunming, on a sultry summer afternoon, I went to Daguan Park to see the Daguanlou, one of the top ten famous buildings in China. However, as soon as we entered the gate of the park, a strong wind swept past, and heavy rain poured down. Fortunately, there are pavilions and pavilions in front of me, and fortunately, the heavy rain lasts for only ten to twenty minutes. It is even better that the Daguan River, which runs through the garden, leads directly to the Dianchi Lake Caohai. In just a while, the rainwater accumulated in the garden will be empty. The dark clouds, rain and fog stayed overhead for a while, and the sultry air suddenly became refreshed. Blue skies, white clouds, and clear skies came just like a heavy rain.

Daguanlou Park, also known as Jinhuapu, is located in the southwest of Kunming City. The main body of the Daguanlou in the park is a wooden structure building with triple eaves and glazed berms. The Daguanlou was first built during the Kangxi period of the Qing Dynasty, and has been repaired and rebuilt several times to become its current structure and scale. Ma Rulong's "Notes on the Reconstruction of the Daguanlou" in the fifth year of Tongzhi of the Qing Dynasty (1866) recorded: "Kunyuan has many mountains and little water, so Dianchi Lake is called Jushi Yan, and there is a pool on the edge of the pool, which is called Jinhua, because it is close to Taihua." Daguanlou was announced as a key cultural relic protection unit in Yunnan Province in 1983 and as a national key cultural relic protection unit in 2013.

The Daguanlou was originally built by officials and gentry in Kunming for their own enjoyment. Following Chinese cultural traditions, officials and gentry were all arty and wrote some poetry couplets upstairs. Most of the content were ordinary words that sang praises and whitewashed peace and prosperity or recited the wind and the moon to express the sorrow of separation. Unexpectedly, during the Qianlong period, a humble scholar named Sun Yanweng, who had been impoverished all his life, came. The man broke away from ordinary customs and wrote it with a stroke, and a shocking 180-word couplet was born.

The first couplet says: Five hundred miles from Dianchi Lake, running to your eyes. Wearing a turban on the shore, I like the vast expanse of space! Look: The east is a majestic spirit, the west is a spiritual instrument, the north is winding, and the south is a beautiful beauty. Why not choose to climb? Take advantage of the crab island and Luozhou to comb the wind and fog around the temples; add some green feathers and danxia to the sky and reed ground. Mo Gufu: There is fragrant rice all around, thousands of acres of sunny sand, hibiscus in the ninth summer, and willows in the third spring.

Second couplet: Thousands of years of past, keep it to your heart. Throw the wine into the air and sigh who is the hero? Thinking: The Han Dynasty used building ships, the Tang Dynasty used iron pillars, the Song Dynasty used jade axes, and the Yuan Dynasty used leather bags. He made great efforts to move mountains and painted buildings with beads and curtains, but he couldn't cover the evening rain and morning clouds. He broke off the stone tablets and monuments, and gave them to the sky and smoke. Only won: a few pestle and sparse bells, half a river fishing fire, two rows of autumn geese, and a pillow of clear frost.

The first couplet writes about climbing the Daguanlou and seeing the scenery around the "Five Hundred Miles of Dianchi Lake". The second couplet expresses infinite emotion about Yunnan's "thousands of years of past events". It blends emotions and scenes, and the antithesis is neat and grand. The length of 180 words makes it the first long couplet unseen in history. Its eloquent and majestic momentum has impressed poets and literati in the world. It is known as the "best long-term couplet in the world". Kunming Daguanlou has also been listed among the top ten famous buildings in China.

The classic-shaped pavilions such as Louwaigou in the park are built along the Daguan River just like the Daguanlou. They complement each other and together form a beautiful garden scenery.

In 1998, in order to welcome the 1999 World Horticultural Exposition, the governments of Yunnan Province and Kunming City invested 25 million yuan to expropriate 197.4 acres of land near the west of Huapu to open the Daguan West Garden. So far, Daguan Park has a total area of 47.8 hectares, including 23.1 hectares of land and 24.7 hectares of water. In the newly opened park, the added modern horticultural elements enable the entire 4A-level scenic spot to integrate ancient and modern times, connect China and the West, each according to its characteristics, without separation, multiple but not chaos, and strange but impressive. At present, Daguan Park has a tourist area with the theme of Changlian History and Culture. It is divided into three parts: Near Huapu Cultural Relics and Monuments Scenic Area, Nanyuan China-West Combined Wall Garden Scenic Area, and Xiyuan Modern Garden Scenic Area. It is already a large-scale scenic spot on the northern bank of Caohai in Dianchi Lake.
