2. Correct your child's pronunciation mistakes: Correct your child's pronunciation mistakes in time. You can put your finger on your lips and let your child imitate the correct sound.
3. Learn Pinyin: Let children master Pinyin, which will help them pronounce correctly. You can teach pinyin knowledge through songs and games.
4. Practice mouth shape and tongue position: Correct pronunciation requires correct mouth shape and tongue position. Children can practice pronunciation in front of the mirror and observe whether the mouth shape and tongue position are correct.
