The ruler is made of pure copper, with three characters "不动心" engraved on the front, which is an important argument of Yangming culture in self-cultivation in life. The measurement unit is marked on the back using the ancient counting method, which is to restore the practical application of "ruler" in ancient times.

Ruler means "discipline". Yangming ruler means to keep the principle of heaven and "discipline" human desires. One is to measure one's own goodness from "filial piety", and the other is to give up selfishness and be unmoved.
