Kaifeng, located in the east of central Henan Province, was called Bianjing in ancient times. During the Spring and Autumn Period, Zheng Zhuanggong built a "Cangcheng" here, which was later named because of its cultural meaning of opening up territory. In 36 1 year BC, Wei moved its capital from Anyi to this place (called Daliang), which was also called Bianzhou in Sui and Tang Dynasties because of its proximity to Bianshui. At the end of the Tang Dynasty, Zhu Wen abolished the emperor of the Tang Dynasty, and established Hou Liang, with Bianzhou as its capital, renamed Kaifeng House. Later Jin, Han and Zhou Dynasties also established their capitals here, which is called Tokyo. In 960 AD, Zhao Kuangyin launched a mutiny in Chen Qiao in the later Zhou Dynasty, seized political power, established the Northern Song Dynasty, and made Kaifeng its capital. During the Northern Song Dynasty 168, Kaifeng entered a period of prosperity, with a population of1000,000, which was called "the capital of the capital is 80 Li", and it was said that there was one Jiangsu, two Hangzhou and three Bianzhou.
