Zhuangzi doesn’t really speak about good vs evil as far as I remember, but they do include a similar concept as the right one. In the old days, the ancient ones lived in perfect harmony, but then later on people started living unnaturally (unaligned with the Dao) and things like war and greed popped up. If one follows the Dao one can return to that natural state of being. As far as I understand it of course.
