My graduation dissertation was "The Implementation of Computer-Assisted Language". That was a period that I spent most of time to study very hard in my life. 8 years ago, there were no iPhone, no Facebook; we surfed on the internet just for fun, for daily news, for chat, for simple games; even using computer for education was not the mainstream and not convenient. I was too young to feel the importance of this subject, just because of my thesis instructor designated me to do it. I never thought that one day I will continue this theme in my work, and to promote it, I feel incredible, and the fate of joy.
