Zhchsh joke

You can't tell a flat tongue from a sticky tongue. Z, C and S are flat tongues, while zh, ch and sh are sticky tongues. Flat tongue sound means that the tip of the tongue is close to the back of the upper teeth, and tongue-twisting sound means that the tip of the tongue rolls up against the upper jaw. The best way to practice fluent Mandarin is to practice. Pay attention to the difference between flat tone and upturned tone when speaking. You can also read the article to practice. When reading, you should pay more attention to mark the places that are easy to read wrong, remind yourself that it won't take long to practice like this, and you can also pay more attention to the announcer's pronunciation and learn to communicate with people who speak Mandarin around you. In a word, as long as we make more efforts in this respect, we will certainly gain something.
