The free class is an audition class, which is true and reliable. At first, I was worried that the free class would be deceptive, so I specially checked the evaluation online. Everyone says it's true, and many friends have experienced it. I'm relieved to see netizens say this. Later, after listening to a week's audition class on Dapeng Education APP, I found it very appetizing and signed up. Now study hard ~ Are you satisfied with my answer?
