This article discusses mainly (on) the interpretation of Daoism by Martin Heidegger and Gunter Wohlfart. Heidegger represents the deepest dialog with Daoism between German philosophers in twenty centuries. His aim is, through the dialog with Daoism, to use the concepts of Daoism to enrich his own thought. Wohlfart on the contrary goes deep into the kernel of Daoism thought. Although he does not know Chinese very well, he refers to German, English and French literatures about Daoism. He also attempts to read Laozi word by word with Sinologists. That is why there are many insights in his works. This article is divided into four parts: 1. Heidegger's reception of Daoism: the free resonance by philosopher 2. The reception of Daoism by Wohlfart 3. The interpretation of Taoism by Heidegger and Wohlfart 4. Conclusion: The transcultural problems aroused from the philosophical research of Daoism.
