Nijmegen was 2 thousand years old in 2005. very old city. Roman built the first neighborhood there.
About PhD study. my opinion is if you really like the topic or the dicipline, it is very good idea to study abroad.and Nijmegen is a very good place to study. Otherwise, it is better to stay in China.
Holland is a very nice country & I like it very well. I have very good colleagues here and it is a good chances for me to expand my own network. not only academic network but also some other aspects.
