The Richter substitution principle is a supplement to the "open-close" principle. The key step to realize the "open-close" principle is abstraction. The inheritance relationship between the base class and the subclass is the concrete realization of abstraction, so the Richter substitution principle is the specification of the concrete steps to realize abstraction. --From Baidu　　霍元甲有两挚友，文的是发小农劲荪，他留学日本，广识博学，国势、外侮的事知无不言，对霍元甲影响深远。武的是北京顺源镖局镖头大刀王五，王五常与他切磋武艺，霍元甲得益不少！The heel is thickened, which can increase the buffer when landing to a certain extent during movement, thus reducing the reaction force.
