句式 - Chinese Sentence Patterns

You know hundreds of Chinese words. So why does forming a sentence still feel impossible? Most apps hand you flashcards and hope grammar sorts itself out. It doesn't. You end up with a head full of vocabulary and no idea how to string it into something you'd actually say. DouDou Chinese (句式) fixes the real bottleneck: sentence patterns, not word lists.
