Lubanchi Gate Ji Shu

Generally, there are 3-to 3-meter gates in line with the size of Luban. Generally speaking, 3m 2 1 is the best size, and 123 and 32 1 are relatively leisure. It is generally written in the Tao Te Ching that the Tao gives birth to one life, two lives, three lives and three things, and 123 is endless.
