The "shi...de" sentence pattern, as one of the frequently occurring sentence structures in Chinese, is particularly complex, making it a challenging linguistic point for Vietnamese learners to grasp accurately. This paper aims to delve deeply into the performance of Vietnamese students in acquiring this sentence pattern.
