Is "Harry Potter series movies" correct in English?

Self-introduction Please help me with the words and grammar I'm Han, a 24-year-old sports fan from China, now learning English and maybe someday French. It might be a little hard for me to talk in English, but reading is just fine. I really want to find out a way to improve my spoken English. I think I'm generally easygoing and communicative. It would be great to have an English speaking friend who want to learn Chinese. More about me: I majored in Chinese language and literature, having an 1st level certificate in Mandarin Proficiency Test and teacher certification as well. Now I work as a secretary in a company. I'm interested in linguistics and Chinese ancient literature. I'd like to write metrical poems when I have inspirations. I'm reading The Three-body Problem(a sf novel by Liu Cixin) recently. I'm a big basketball fan and Spurs is my favorite team in NBA. Furthermore, I play volleyball and table tennis. I like PC games and I have a Steam account. It's fun to play with friends.
