1，z c s:

When z c s is pronounced in many areas of Shandong, the tip of the tongue sticks out between the upper and lower teeth and becomes an interdental sound. There is no interdental sound in Mandarin. When correcting, the upper and lower teeth should be gently meshed to prevent the tip of the tongue from protruding, thus making a pure pre-tip sound. In some parts of northeast China, warping and warping are mixed, and some z c s sounds are pronounced zh ch sh.

2、zh ch sh:

The retroflex of the tip of the tongue, zh ch sh, is easy to be voiced in some dialect areas in Shandong. That is, the front edge of the tongue is in contact with the gums of the upper teeth, the tip of the tongue is separated from the hard palate, the front part of the tongue is raised and moved close to the hard palate, the tongue surface is depressed to form a small hole, and the lips protrude slightly forward, making a sound called tongue flap sound. When correcting, the tip of the tongue should be tilted, touching or close to the hard palate, and a pure backward inclination of the tip of the tongue should be issued.
