This collection mainly discovers the conflicts between imprisonment and freedom. It is a hot topic for China these days because of the riot of Hong Kong. The situation in China is just that people here have a relatively free hand in deciding what they are going to do while actually being controlled by the government. It reminds me of gravity under which you can jump without limitation but finally be forced to fall on the ground. I also consider policy as a kind of texture. Policy permeates all thing in your life just like the clothing we wear everyday which embrace us and influence us.
