This film had a serious divestment problem because the director rejected the investor's request to alter the script. At last the director had to use his own money to finish the film. when finished, there was no money for advertising. However, the film earned a good reputation after the premiere and drew many fans in a very short period of time. These fans called themselves zi lai shui (tap-water), which means they are willing to advertise the film on social media for free.
