Generally speaking, Henan belongs to the north, and a small part belongs to the south (Xinyang City, Nanyang City, Henan Province). The north and south of our country are divided by the Qinling Mountains and Huaihe River. Most of Henan is north of Huaihe River in Qinling Mountains. There is only Xinyang in the south of Huaihe River, and Nanyang has an excellent geographical position, just south of Qinling Mountain and north of Huaihe River. So in general, Henan is divided into North China. Moreover, in terms of cultural customs, Henan is close to Shaanxi, Shanxi and Shandong, and far from Hunan, Fujian and Guangdong. Historically, most areas in the south of Henan Province were dominated by the culture of the Yellow River basin, while areas south of the Yellow River, such as Hubei Province, were dominated by the culture of the Yangtze River basin, so Henan belongs to the northern province.
