Is CC English better or Tian Tian English better?

Hehe, hello, Tian Tian. English is better. Why? That's because the teaching quality in Tian Tian is good. I have attended cc's class. Most importantly, some educational institutions have joined forces with Tian Tian, which means that Tian Tian has passed the certification of educational institutions, and some majors have only joined forces with Tian Tian ok.
