When mainland China simplified Chinese characters and implemented them across the country in the 1950s, the writing of characters on both sides of the Taiwan Strait has become quite different. The most well-known difference is the number of strokes in traditional and simplified characters. In the process of learning modern Chinese characters, it is obvious that although the number of strokes in some fonts on both sides of the Taiwan Strait is the same, when comparing the fonts, there are differences in stroke shapes, such as the radical part "儿" or "几", and the "丸", which"丶"should be under or through the "丿".In this situation, learners are prone to make mistakes in writing, and even Chinese character teachers are troubled. It is often difficult to give a satisfactory answer to why the glyphs are written in this way. Therefore, we can only start by exploring the origin of Chinese characters and connect their meanings through glyph components. When teachers clearly understand the theory of character structure, they can naturally explain the reasons for the change of glyphs; learners can also clearly understand the differences in Chinese characters between the two sides of the Taiwan Strait, and at the same time, they can write Chinese characters correctly without getting confused.
