Yu pinyin is pronounced as follows: for the first tone (yū), pedant; for the second tone (yú), fish; for the third tone (yǔ), feather; and for the fourth tone (yù), yu.
Because (ü) sees j, q, x, and y with two dots removed, yu=yü, and yu is a holistically recognizable syllable that doesn't need to be spelled out in one breath.
Yu is one of the overall recognizable syllables, which does not need to be spelled out, but only recognized as a whole. In pinyin, there are 16 whole-reading syllables in one ****, which are: zhi, chi, shi, ri, zi, ci, si, yi, wu, yu, ye, yue, yin, yun, yuan, ying. these syllables don't need to be spelled out, but only recognized as a whole.
Yu is relatively simple to pronounce, requiring only the merging of the y and ü phonemes. When pronouncing yu, the lips are slightly rounded and the tip of the tongue is pressed against the backs of the lower teeth, leaving a small amount of air in the mouth, and then the tip of the tongue is quickly lifted up to produce the ü phoneme, followed by a slight opening of the lips to produce the y phoneme. The whole process of pronunciation needs to be quick and consistent, all in one go.
The four tones of yu are also relatively simple: ping-sheng, yang-sheng, Shang-sheng and de-sheng. When pronounced in different tones, you only need to slightly adjust the tone and pitch during pronunciation. For example, when pronouncing yū in the first tone, you need to raise the tone slightly; when pronouncing yú in the second tone, you need to lower the tone slightly; when pronouncing yǔ in the third tone, you need to raise the tone slightly and then lower it; and when pronouncing yù in the fourth tone, you need to lower the tone slightly and then raise it again.
