I felt happy every time when I was receiving e-mails from the Kungfu lesson system, it makes me felt under taking care of . Rios and kfe_ying always be patient to me, if I had asked any questions on learning process, especially Rios. He gave me a lot of encouragement and achievements which are very very important for me to insist on hard working in English. I also enjoy the time that I wrote my requirements in English, and yet Rios's feedback were in English. It's really helpful, because of this, I could reply the e-mail by using English. Hope it make sense.
