Site selection
We chose to shoot in a private room in a Chinese restaurant. The specific environmental requirements of the venue are as follows: ① the area of the private room is close to 15 square metres (4 m × 4 m); ② the round turntable table and chairs in the private room are placed in an orderly manner; ③ the lighting in the private room is bright, soft and moderate, and cannot be too bright or too dark.
