Documentary makers in China have encountered a bottleneck. The mainland started developing documentaries over a decade ago and the timing couldn't have been better. It was the time of reform and opening up. As long as you didn't step on the government's toes, good, moving subject matter was there for the taking by anybody willing to put in a little cerebral effort.
以中國大陸紀錄片工作者遇到的瓶頸來說，大陸的紀錄片在十幾年前開始發展，由於時機對，加上改革開放，只要內容不威脅到政權，多花一點心思就可以隨處取得很好的題材，拍出感人的紀錄片。
