What excellent traditional culture and national spirit does Laozi express?

Its core idea is "inaction" in the Tao, and human nature should follow the law and heaven, so doing inaction and even doing everything. Laozi's way is mainly to let nature take its course and obey the law without acting rashly. There is also a dialectical relationship. Laozi emphasized guarding the weak, like water, but not cowardice. Weaknesses and strengths can be transformed, and the key is to master them.
