Introduction to the simplification of Chinese characters / 汉字简化简介
Some may mistake that Simplified Chinese is the disruption of the language, since it “forced the change of the long-term stable shapes” and “are leading to the extinction of the essence of the language”. Hence, the true visage of the simplification needs to be presented. 有人误认为简体字是对汉语的破坏，因为它“强行改变了长久使用的字形”、“将汉语的精髓导向消亡之路”。因此，有必要对汉字简化的本来面貌作出阐释。
