Every city has its own advantages and disadvantages. Hangzhou has a pleasant environment, rich urban heritage, many universities, a good academic atmosphere and a good economic foundation. Every year, candidates compete for registration, and college students find jobs after graduation with fierce competition.
Ningbo is a young and energetic city with a booming economy and full of opportunities. Relatively speaking, the competition for graduation work is relatively relaxed.
Also, if you look at your favorite professional field and choose a city, such as studying foreign trade, then Ningbo Port City is certainly better.
You have to decide according to your own situation. I hope my answer is helpful to you.
