Zhengzhou is different from Shenzhen.

Zhengzhou, the capital of Henan Province, is located in the hinterland of China, among Kyushu, with the Yellow River in the north, Huanghuai Plain in the south, Kaifeng in the seven dynasties in the east and Luoyang, the ancient capital of the nine dynasties in the west. The city covers a total area of 7,446.2 square kilometers, and now governs 6 districts, 5 cities 1 county. Shenzhen is a coastal city in China, with 6 districts and an area of 2,020 square kilometers. With a population of more than 7 million, most of them come from other places, so Shenzhen is called "immigrant city". Broadly speaking, the area of Shenzhen is not as big as that of Zhengzhou, but the prosperity of Shenzhen is incomparable to that of Zhengzhou.
