Buying mandarin textbooks

Hi everyone just wondering if anyone knows any good bookstores where one can buy some textbooks to learn/study chinese?

I’m not taking classes at the moment and don’t really plan on it. Been studying a lot lately and have some taiwanese friends who i can practice with but looking to get more into grammar/more advanced vocab.

if you live in Taipei, go to NTNU’s bookstore on Ho-ping E. Rd. near the Shih-Ta Rd. traffic light.
That bookstore should have all the Chinese-level textbooks used at NTNU’s Mandarin Training Center. Ask for where 語言中心書店 is.

If you are in Hsinchu, I know NTHU bookstore has some options.

Lucky is popular near Shida. But Eslite has huge variety.

Lucky Bookstore
106, Taipei City, Da’an District, Section 1, Heping East Road, 182-3號

the eslite stores generally have most of the usual suspects. their flagship store near 101 has a lot of books but their other stores have most of them too. the main two series you will find here are practical audio visual chinese and a course in contemporary chinese.
