Xi 'an has a relatively strong economy and belongs to the provincial capital. It is a central city in the northwest of the country. Rich educational resources, top-notch students, and good basic education.

Yancheng's economy is relatively developed, which is 6 times of Xi 'an's GDP. But there are too many places where Jiangsu's economy is better than Yancheng's, and many educational resources are concentrated in big cities, so Yancheng's basic education is not as good as Xi 'an's.
