"Mud Fire 1999" is set in the northern industrial city "Heihe" from 1992 to 1999. It focuses on the portraits of the lower class under the restructuring of state-owned enterprises and the wave of layoffs. It uses rough brushstrokes to outline a group of people struggling in the quagmire - carrying scars and desires, they are looking for warmth and a way out in the folds of the times. The whole work has a solid structure, full of details, and combines the texture of the times with the depth of humanity. It is a highly infectious low-level narrative masterpiece.
