刘狄青，Tony Liu is a film buff, who directed the short film No Door in 2013 which will be released on August 16,2014. The purpose he makes the movie No Door is to dwarf movies made by the same generation. Tony Liu made short film No Door with self-confidence and ambition. He learned a lot of filming techniques and skills from professional filmmakers, Hollywood shows and relevant books, etc. He said: The theme of the short film No Door I chose doesn't match my style. I have thought about to make a movie introducing spirituality, talking about a story that is related to positive things. So I kind of regret to made such movie. Nevertheless, that's exactly the Hollywood movie's format right? I was just trying to make a movie that can give audiences a shock though. But anyway, I enjoyed that days when I was with my friends to build this work together and I'm glad now the work has been completed. So, thanks, thanks those who support me in this entire process and thanks you all for giving me positive and negative comments, which make me better, leading me to do a better job.
