Chinese character writing is one of learning difficulties for Korean learners of Chinese as a second language. There are not many studies on the stroke writing of Chinese characters by Korean learners of Chinese as a second language. Based on the elementary handwritten Chinese characters in the “Chinese Proficiency Grading Standards for International Chinese Language Education”, this paper conducts a stroke analysis, and combines the whole-process interlanguage character database and the interlanguage text corpus of international students to conduct an investigation, and explores the problems existing in the Chinese character strokes of Korean learners of Chinese as a second language. The research results show that elementary handwritten Chinese characters with 7 strokes or less account for 60% among elementary handwritten Chinese characters, and these Chinese characters are easy for learners to acquire. The error rate of Chinese characters with 1-7 strokes is 2.8%, while the error rate of Chinese characters with 8-14 strokes is 6.4%. The error rate of Chinese characters with 8-14 strokes is significantly higher than that of Chinese characters with 1-7 strokes. This paper analyzes the causes of the writing problems and puts forward suggestions for teaching character strokes, hoping to provide effective help for teachers, thus helping to improve the Chinese character writing level of Korean learners of Chinese as a second language.

For a long time, the teaching concept of “monism” has made the field of international Chinese teaching focus on “words”, not “Chinese characters”. Chinese characters that are difficult to teach and learn have not been effectively improved. In 2021, the introduction of the “Chinese Proficiency Grading Standards for International Chinese Language Education” set a new direction for international Chinese education, and the practice of listing a handwritten Chinese character list separately for the first time also reflects the importance of Chinese character teaching. Long before the introduction of the “Grading Standards”, a small number of international comprehensive Chinese textbooks had compiled handwritten Chinese character lists, but there were many handwritten Chinese characters that were not included in the “Grading Standards”. This kind of Chinese characters or have a large number of strokes, or the shapes of the strokes are more difficult, or the structures are more complex, or the ability to form words is weak, etc., which is exactly the opposite of the characteristics of the “Grading Standards”. According to the results of the relevant analysis, it can provide practical reference for the compilation of Chinese characters in textbooks in the future.
