This work was commissioned by Hainan University and included as one movement in the symphonic suite "Tropical Rainforest". "The sheltering bamboo tiles, the carrying bamboo raft." The overall conception of this piece is based on the original sound characteristics of the national-level intangible cultural heritage project: the Hainan Li ethnic group's "bamboo and wood”instrumental music. Utilizing the solo instrument marimba and other percussion instruments, the composer attempts to create a rich and colorful musical spiritual world of the Li ethnic group. Additionally, the melody of the Hainan Li ethnic folk song "Long Time No See, Long Time See" appears prominently or subtly throughout the entire piece, serving as an important source of melodic pitch for this composition.
