In "Shadow" stills, the appearance of snow in white in Sun Li immediately sparked heated discussion. In this preview, while maintaining the painting style of ancient ink and wash, what is even more amazing is Xiao Ai's eyes, especially the scene of peeping through the partition wall. With the movement of light and shadow effect, Sun Li's eyes slowly changed. At first, he hesitated and paused, but he couldn't help but open a peep. Then the electric shock was projected into his eyes with the light. You can feel some flash close-ups. Sun Li uses subtle changes in his eyes to express the inner feelings of the characters, sometimes sharp and sometimes gentle, and sometimes he wants to say goodbye, seemingly quietly, but all the scenes are in his eyes, and wearing gauze clothes with clear water and ink style adds classical charm.
