The pronunciation part of tongue-wagging should be that the tip of the tongue is upturned, facing (ZH, CH) or near the front end of the hard palate, you try to lick it with your tongue gradually from behind the upper teeth. The feeling should be like this: first, it is rough, and this part is the gum (the part of the gum is much more than we thought). Remember, the curvature of this part is not so great, that is, it is not so curved; Then, this part is over, and then there is the part where the radian suddenly increases. In addition to being much more curved than the gums, the touch becomes very smooth, which is the hard palate.

Pronunciation is located in the front of the hard palate, or at the junction of gums and hard palate.

Many people say that I found the right position, but why is the voice unnatural and pretentious? Do those CCTV announcers really stick to this position? In fact, their pronunciation is really standard, and there is absolutely no problem with the pronunciation position. The difference between us and them is that their pronunciation is better than ours

They usually retract their tongues, which are tight and won't loosen, because once they are loosened, the volume of the tongue body becomes larger, and the greater the contact surface with the hard palate, the more noisy and unnatural it sounds. They just make the pronunciation position right, and make the contact surface between the tip of the tongue and the hard palate as small as possible, so that the sound sounds clean and clear without losing the richness of the tip of the tongue.
