This is a bit difficult, because there is no way to express it with pinyin and other tools. For example, the pronunciation of "Hao" is between good and backward, the opening and closing range of the upper and lower jaws is smaller than that of "Hao" in Mandarin, and the lip shape at the end should not be too round. "Eating" should be pronounced as "late" and pronounced near the front of the mouth. The "uncommon" in Qinghai dialect is "radian"
",but they are all lip biting sounds, and the international phonetic symbol is" hv (three tones) dv (two tones) ".
For others, you can search the cross talk and sketches of Qinghai dialect on the Internet for reference.
