@masterwu81: @南山 Genuine: "Tao" can be Tao, very Tao; "name" can be named, very "name". "Nothing" is known as the beginning of heaven and earth; "Being" is known as the mother of all things. So often "nothing", want to see its wonderful; often "have", want to see its periphery. These two, the same and different names, the same is called the Xuan. Mysterious and mysterious, the door of all wonders.#tao #culture #Ancient #taoism
