Color: ① The whole film is based on green, and the picture is fresh and natural. For example, when the father and son walk on the mountain path, the green bamboo forests on both sides of the lens not only symbolize vitality and vitality, but also create a fresh, natural and ethereal artistic conception.

② The Dong wedding, red national costume and red bonfire in the middle of the film show the folk customs of the Dong people and symbolize their enthusiasm, sincerity, youth and vitality. The red skirt of the Dong girl is the bud of love, like fire.
