Confusing words are a difficult part of Chinese learning. When we master a certain number of words, we will inevitably encounter a large number of confusing words that have both similarities and differences. Being able to grasp their similarities and differences and using them accurately is the key to improving the HSK score. In this class, we will learn the discrimination methods of confusing words in HSK level 4, master their similarities and differences, expand our vocabulary and improve vocabulary usage skills.
