1. Because Tianyi is in the urban area, the traffic is more convenient and there are more people than Wanda. Although Wanda is also very developed, it is a rich area, but it is close after all. Most students go to Tianyi.
2. Everything you like can be found in Tianyi with high or low consumption, and stars come to Tianyi to do activities from time to time, just like the last time Lin Chi-ling came to Tianyi to do watch brand activities.
But Wanda is also good. I have been there several times. The environment there is better than Tianyi, and Yintai feels much more upscale than Tianyi. Besides, Yintai's cinema is one of the best facilities in Ningbo. You can spend money there once in a while if you want to be extravagant. Oh, and Wal-Mart.
That's all my advice. You can refer to them.
