According to historical records, Qujiangchi rose in Qin and Han Dynasties and flourished in Sui and Tang Dynasties. It is a classic of Chinese ancient landscape architecture. Qujiang River in Qin Dynasty is a natural pool, called Yongzhou, with the famous Yichun Palace. Emperor Wudi of the Han Dynasty was named "Qujiang" because of its vast waters and winding pools and banks. In the Sui Dynasty, when Daxing City was built, Qujiang River was included in the city outline and renamed Furong Pool. In the Tang Dynasty, Qujiang River was constructed on a large scale, the Yellow Canal was digged, the imperial court was opened, the Jiacheng City was built, the Big Wild Goose Pagoda was built, the new gate was opened, and Qujiang Pool became a thousand mu water area, a famous tourist attraction in Beijing and China. Qujiang Liuyin,"Yanta Title", "Xingyuan Guanbanquet", "Cold Kiln Story" and other allusions and legends have made Qujiang Pool more famous. At the end of Tang Dynasty, Qujiang Pool was destroyed by war palaces, and its water gradually dried up. Then it was reclaimed as a field. There was hardly any grand landscape in the garden. In July 2007, Xi'an decided to invest a huge sum of money. According to the historical water system and heritage exploration achievements of Qujiang Pool, a large-scale open garden ecological project, Qujiang Pool Site Park, covering an area of 1500 mu, integrating historical culture, heritage protection and urban recreation, was planned and constructed. As a key construction project in Xi'an, it will be completed and opened one year later. Qujiangchi Site Park highlights the strong wind of Qin and Han Dynasty, inherits the source of Sui and Tang dynasties, lakes continuity, is the perfect reproduction of the historical prosperity, is also the triumph of Xi'an "Royal City Renaissance Plan", known as the model of the construction of human Xi'an, the integration of ancient and modern, and the harmony between man and nature.
