In the 4.0 era, besides English, Chinese is also one of the common languages in the world. The more developed the world economy, the deeper international integration will be. Therefore, people’s demand for learning foreign languages is increasing, especially Chinese and Chinese characters are an important step in the process of learning languages. Through my own practical experience and more than 20 years of Chinese teaching experience. We find that Chinese character recognition ability includes shape, sound and meaning, which is an important point to evaluate learners’ Chinese ability and the basic foundation of reading and writing. Because Chinese is a language with a square character structure, a Chinese character can be composed of one or more strokes, so memorizing and writing Chinese characters brings many difficulties to learners of Chinese characters. Language experts also believe that recognizing and decoding letters is the basis of reading comprehension. Learners must recognize letters through basic features, and then learn meaning through gestures and information conveyed by Chinese characters. At the same time, many studies show that memorizing and writing Chinese characters is very important for Chinese learners.
