The main composition of this work is the texture of flowing hydrology. In the picture, three elements including a swimmer, diving dog and fish swimming in between decorate separately and enrich the festive atmosphere in the swimming pool. The reuse of recycled materials and the drawing of elementary school students have stimulated the creativity of work elements with colorful shaping, presenting the rhythmic atmosphere of the free swim. Two pieces of work are installed on the entrance wall toward the hall altogether around 15 meters long, and it is similar to the surrounding scenery of ecology in the water system.
