Children's interest is the pursuit of many artists, and it is also the pursuit of pure and true aesthetic realm. The designer used lines to outline a poetic painting of the jungle. The monkeys played in the jungle, bending the tall and straight palm trees, and the broad leaved vegetation floated in the wind... The plants and animals were like both shape and spirit, full of interest. The texture with different structures and rich decorative meanings is composed of lines, which are dense and delicate. The colorful wall cloth is interwoven with different colors of yarn. The designer expresses his love for the jungle and the changeable natural phenomena with lines, as if he were in the lush jungle.
