What makes me confused is that what is the exact meaning of "Cross-cultural Experiences"?
This is asking what you have experienced already. Have you lived in the USA before? Did you learn anything about the culture of USA?
Similarly, did you learn anything about the cultural differences between Edingburgh and China?
You don't even have to focus on the global cultures, there are so many cultures in China that you can talk about too. Have you ever been to a minority ethnic group village? What was different about it? Were there traditions they did that were different from yours, like drumming and dancing? Have you ever went to the country side and observe the people living there? What did you take away from those experiences?
In addition, I am not sure how could I explain "in which way will my cross-cultral experiences contribute to the classroom".
In this age of technology, your "updated" information becomes old the instant the new ones appear. You do however, bring to the table your cultural and economical experiences. What is it like living in China with only $1 per day? Personal experiences only go so far in a classroom, unless they're really impressive ones. There is no best or right way to answer this, it all depends on how well you write. Most people say they bring to the classroom their personality, their hard-working, perseverance, and a bunch of other things. But don't write what others write, because this essay wants you to STAND OUT.
