We created an app based on a document that categorizes the assigned Chinese characters according to level for the National Chinese Character Proficiency Test, a Chinese character certification test hosted by the Korean Language and Literature Association. Accordingly, it was designed with the purpose of helping you accurately understand the structure and order of each letter. In order to learn Chinese characters for each level from level 8 to level 1, you can learn, write, and review pronunciation, words, idioms, radicals, abbreviated characters, simplified characters, etc. by item.
