There are two situations when pronouncing. One is that the pronunciation is clear, the mouth is open, the mouth is slightly flat, the tongue is upward, and the sound is brought out from both sides of the tongue by the airflow, and the sound is crisp, such as the pronunciation of words such as long, life and plan.
