Do you know where the border line is, which divides China into the south and the north of China? Some people think it is in Zhengzhou, Henan province, but it is wrong. The correct answer is in Huai’an city. The Huai River is just this border line. We call the south of China from the south of the Huai River. On the contrary, we call the north of China from the north of the Huai River.

One bridge has been built across Huai River. It is very interesting that it colors red from the south and colors blue from the north, because the red represents hot of the south and the blue represents cold of the north. It is very funny, isn’t it?

Even though it is dirty, it is true that the border line is just in Huai'an.

The border line of China is in Huai'an.
