Yinchuan has been built for 2121 years. Due to its three major characteristics of the ancient capital of Western Xia, Hui ethnic customs, and the Jiangnan region, it was announced by the State Council as the second batch of national historical and cultural cities in 1986, ranking among the 110 historical and cultural cities in the country. There are numerous historical and cultural relics distributed in the ancient city, which reflect the development and changes of various historical periods in Yinchuan. With the passage of time, numerous historical and cultural relics in Yinchuan City have gradually disappeared into the long river of history. But Beitahu Park still has a high status. Spring and summer are the most beautiful seasons in Beita Lake. The park trees are green and the flowers are red, the path is fragrant and far away, the water birds play on the lake surface, the fish fly shallow at the bottom, and the time and space atmosphere is the most beautiful. The beauty of Beita Lake lies in the tower, in the trees, in the water, but more in the culture. Amidst a cluster of ancient buildings, the North Tower rises from the ground, towering into the clouds, with nine floors visible throughout the city. The tower is in a four sided shape, made of bricks and stones, with steps inside that can rotate upwards. Each floor has arched windows for viewing the scenery, and wind chimes hang on the eaves of each floor. The sound of the wind is pleasant and beautiful. The North Tower is famous far and wide, and tourists are also constantly coming. But the busiest place is still the square in front of the tower. Every morning and evening, leisure and exercise people gather here, either singing and dancing, or singing loudly. Dancers feel like no one else, enjoying themselves, and the audience keeps cheering one after another... This is the most popular characteristic scenery of Beita Lake. There are many and unique types of trees in Haibao Park. The white poplar trees are tall and lined in rows, while the willow trees droop and float, standing along the lake. The branches of Elaeagnus angustifolia have curved white leaves, and the fragrance of flowers is refreshing. The mulberry branches are strong and winding, and the leaves are large and emerald green. The stems of locust and Chinese locust trees are thick and thin, with green leaves like a canopy, and thick shade blocking the sun. The fruit of the Chinese flowering crabapple is pressed against the branches, with a green tinge and a reddish hue. There are the most types of pine and cypress, with varying sizes. The tall ones are towering and upright, while the juniper is tied into various shapes, like a green cloud, dense and airtight. The dragon and cypress crawl on the ground, winding like a snake. There are also many unnamed trees with unique shapes that adorn the garden. Under the shade of the trees, ancient buildings and pavilions appear particularly quiet and elegant. The water here is clean and soft, with a blue-green color. There are two large lakes in the north and south, occupying two-thirds of the park. The water surface is open and of varying shapes, and it is connected to the Diannong River in the north. The two lakes are sometimes wide and narrow, with curved water surfaces connecting them. Strolling freely, but seeing a deep pool here, lotus leaves float in the water, and there is a small canal with surging waves and currents. There are various types of bridges, either lying or bending, with scenery in the pavilion, streams by the roadside, and various strange stones scattered everywhere. The most distinctive feature is that the surrounding area of the lake is covered with reeds, with green waves and waves when the wind blows. The water moves and the reeds shake, echoing each other. Water birds shuttle through it, appearing and disappearing, and the bird's language is pleasant and pleasant, creating a lively atmosphere. After the awakening of insects, the weather gradually warmed up, and migratory birds migrating north gradually flew to Ningxia. Every spring and autumn season, tens of thousands of migratory birds are welcomed. The integration of historical sites, pagodas, parks, and migratory birds has become a favorite place for locals to visit on weekends.
