Determination of the main ring is the key to name a polycyclic structure. A method that features a "cutting the shortest bridge, uncovering the largest ring" was introduced. This method facilitates the main ring determination of a polycyclic structure. And this method is reliable and easy for students to master.

Key words: Polycyclic structure, Nomenclature, Main ring determination, Cutting the shortest bridge, Uncovering the largest ring
