What do you recommend for high school students' graduation trip?

I feel that it is really good to arrange some trips properly by using high school, which can relax my mood and broaden my horizons. I would like to recommend two distinctive domestic destinations, Datong, Shanxi and Quanzhou, Fujian. Why do you recommend these two places? Because first of all, traveling to these two places is not affected and restricted by any season, and all seasons are more suitable. Secondly, there will be no bustling tourists in these two places. Third, both places have strong cultural connotations. Finally, both places have great local food. It can be said that there are fun and food. Isn't it great?
