Lin Xiao, Master of Philosophy. While his classmates were entering universities, research institutions or famous companies one after another, he chose to wear bright yellow delivery uniforms and became a "yellow shirt traveler at night". It was not forced by life, but more like a self-exiled field investigation - he wanted to touch the real pulse of the city hidden by neon lights while running around at the lowest level.
But he didn't expect that what he touched was another kind of "coldness".
