As China develops and grows, there are an increasing number of Chinese language learners worldwide, and Chinese learners are becoming more and more interested in the Chinese Proficiency Test (HSK). The Chinese Proficiency Test (HSK) is also continuously evolving and improving. After more than 20 years of development, it has gradually been recognized by Chinese language learners at home and abroad. However, due to the short launch time, the existence of deficiencies is inevitable. But the IELTS exam was introduced in China in 1987 and has since amassed a wealth of knowledge and practice. Its framework is similar to HSK, so it can be used for HSK propositions and tests. One of the most challenging aspects of teaching Chinese is writing which involves the writing of Chinese characters, most Chinese learners have difficulty in writing. This paper mainly compares the test design and content in the writing part between HSK and IELTS, analyzes the effectiveness of the writing part of HSK, and puts forward some reference suggestions for the future writing test proposition and implementation of HSK.
