I chose to use the Chinese pattern "Ruyi Pattern" to simulate the crack. The "Ruyi pattern" originated in the Wei and Jin Dynasties of ancient China, symbolizing all good things and peace and smoothness. I chose this pattern because I hope that those who were injured in the war will all be safe and smooth in the future. Although it has caused indelible harm, it is hoped that the peace and tranquility after the war can bring some healing to the wounds.
