Spray refers to the foam aroused by turbulent waves. In Jin Bo's works, waves have a deeper meaning. It is the spiritual symbol of mankind's unremitting struggle for life and the symbol of human's continuous progress and pioneering spirit. The surging waves contain the infinite energy of the ocean, and also reflect the courage and determination necessary for human beings to explore the unknown and climb the peak bravely.

The waves in Jin Bo's works also imply the purity and kindness of human nature. Through the reflection of sunlight, the spray shows various colors and gives off dazzling light. Jin Bo echoes the beautiful side of human heart through the image of waves. Comparing the spray to the miracle of life shows that we should cherish life, carry forward good quality and create more beauty for society.

Spray is a belief to conquer difficulties. The waves described by Jin Bo are full of challenges and adventures, and also symbolize the indomitable spirit of human beings when they overcome difficulties and surpass themselves. The sound made by the waves hitting the stone makes people realize that difficulties and setbacks are inevitable on the road of life, but only by going forward bravely and strengthening their beliefs can we finally overcome difficulties and achieve a great life.
