As a social animal who has been studying and working in Shanghai for 10 years, I think I still have the right to say something. Shanghai is the fairest place I have ever seen. Only if you work hard enough will you get something. The so-called exclusion may be a subjective experience and sentiment as a foreigner. Most Shanghainese won't say that they are deliberately xenophobic. On the contrary, they appreciate young people who are capable, energetic and talented. For a simple example, Shanghai natives often communicate in Shanghai dialect, which may be unacceptable to some foreigners. They think they are exclusive, but people speak Shanghainese just like we speak dialects, so:

(1) Calm down. Look at everything with an inclusive and peaceful attitude.

(2) Seek inward. Always know what you want, don't care about other people's ideas and eyes.

(3) Avoid generalizations. Even if you meet someone who doesn't know how to respect, remember that it's just a person, so just stay away from him.

(4) Feel everything here, teachers, classmates, colleagues and even strangers.

Take your time to savor your learning journey.

I wish you success in your studies and flowers bloom all the way!
