Design philosophy: the instrument carries the Tao and the Tao follows nature.

"Instrument Tao" comes from the
I Ching: the upper philosophy is the Tao, while the lower philosophy is the instrument. Tao refers to the method and the idea, and the instrument is the instrument and the items.

"Instrument carries Tao" is the concentrated reflection of the relationship between instrument and Tao, and also the pursuit of the realm of creation in Chinese traditional culture. It integrates ideas and concepts into objects, strives to make the design of objects conforming to the inherent law of creation, and expresses specific cultural connotations, so as to realize the unity of Tao and instrument.
