There have always been two ways of normative interpretation of “etc” in Articles 72 and 82: formalist interpretation and substantial interpretation. Formalist interpretation of “etc” tends to be conclusive, which is equal to “That’s all.”；Substantial interpretation of “etc” is incomplete, the equal of “To be continued / added.” After comparing the advantages and limitations of two interpretations, it is deduced that the formalist interpretation of “etc” in Articles 72 and 82 of the Legislation Act can also be incomplete, while the substantial interpretation can be expanded according to the legislative needs of the local government. The two approaches to the interpretation of “etc” should be beneficial to the development of local government and local legislative power.
