The shumu/suma graphic symbol evolved from the mayan pyramid, one of the famous representative buildings of mayan civilization zui. "the earth is not human, but it is human." mayan civilization is one of all known civilizations in which zui is a complete respect for the laws of nature, and that is why the maya have so much knowledge beyond modern civilization. Shumu/sisma - recapitulating mayan civilization explains the manual classic. Shuma made every piece of work in good faith, using the crude zui skin, the plain thread of zui. Each thread tells the glory of mayan civilization and explains the true meaning of working civilization: wildness, primitiveness, silence, self-esteem, and freedom from detention the tactful use of materials such as skin and needle wires, imitation of ancient metals, and the branding of traditional tattoos shapes the better harmony of life with nature. Make it with heart, make it with love. In the line of suma's products, "skin" is not just a material, but rather a story of a law of nature. Each of these products is a combination of crude personality and careful thinking, or wildness, or silence, or warmness, or elegance...
