Did Xiahuayuan belong to Chahar Province before?

In the Shang and Zhou Dynasties, early villages appeared here. In the Qin and Han Dynasties, with the rapid development of iron farming industry and the rapid expansion of agricultural population, the ruling class formally established a county here to strengthen local rule. The confrontation between Liao and Song Dynasties in history was the heyday of the development of Xiahuayuan. According to Liao History, Xiao Taihou and Yelu Longxu, the emperor of Liao Dynasty, coveted the land of the Great Song Dynasty, and visited the south many times. When they saw the dangerous terrain and beautiful scenery here, they built three famous royal gardens in history, namely, the upper, middle and lower gardens, which are still in use today. Since then, emperors such as Ming Yingzong and Qing Shengzu (Kangxi) have visited the Garden in person.
