What are the lighting and photographic styles of Du Qifeng's films?

I personally summed it up as three characteristics: first, the use of wide-angle and ultra-wide-angle, such as gun fire, shows the battle layout well and enhances the sense of tension. Second, supersaturated color and color contrast, usually the color contrast of classic pictures is relatively large, such as black, white, red and green. Third, night lights are used more and are close to life. For example, use street lamps, bar lights, roadside luminous billboards and so on.
