It is mentioned in historical records that Lu Ban has little knowledge of Feng Shui, but he is excellent in the field of carpentry. Therefore, his knowledge of Feng Shui has not been recorded in historical records, and people have neglected that he is still a master of Feng Shui. However, Lu Ban himself recorded his views on architecture, the manufacturing technology of tools, the pattern of architectural design and the influence of geomantic omen in his own "Lu Ban Jing", which provided a good teaching material for future generations to learn woodworking skills until now.
Many woodworking tools we use now were invented by Lu Ban, such as umbrellas, graphite, ladders and saws. The carpenter's special tools, such as rulers and Mo Dou, are all made by Lu Ban. Why Lu Ban was able to invent these things is inseparable from his careful observation of the affairs in life. Take the process of his invention of the saw as an example. Luban went up the mountain to cut firewood. The mountain road was uneven and it was difficult to walk. He accidentally fell down and scratched his hand by the plants next to him. He found that the plants were covered with sawtooth shapes. The first thing that flashed through his mind was how powerful it would be if this shape was designed as a tool for cutting trees.
Luban is a man who will do it when he thinks about it. Now he goes home at once and makes a saw in this way. It saves a lot of time for cutting down trees in the later stage and greatly improves the efficiency. Many of his inventions are inspired by the little things in life, and therefore become the door for architecture to open a new world.
