The are now has Metro station in Chungli so easier access to Taipei attractions. Also Chungli has nice night market and lots of Uni students nearby. Chungli/Pingzhen also lots of nice Hakka food and culture (Pingtung of the North haha). Strong coffee cafe culture, if you go to small cafe and speak Enlgish (and look decent) sure easy to make friends. Lots of cafes in Chungli Metro-Train Station, sogo area and near Uni. Cafes like my Tainan topic cafes full of girls. Northern version of this Cafe in Xinying, Tainan that I Think Women Might Like
I had High School classmate, she went to Uni there so visited sometimes. Nicer than I than I thought, if you go out can make friends since your age is near Uni students age.
