Na Ying was very popular in her early years because she grasped the rise of pop music. Her popularity is entirely due to the turning point of the times. A song was hit by a cow, and then she sat on the queen's throne and sat on the bench until now. Liu Huan is similar to her, but Liu Huan's taste in music is much higher than Na Ying's.
In terms of technology, May is much better than Na Ying. The breath is stable and full of * * *, giving up the strong closure of vocal cords and relying on closure to change the sound is not only unified in sound area but also humanized. May's humanity is different from Na Ying's. Na Ying's humanity is based on words, while Amy's humanity is based on "vocal music", which is why Amy's songs sound simple, but in fact they are extremely difficult.
May was born in an indigenous country. Under the reasonable guidance of Tom Zhang, he not only has solid basic skills, but also has a high appreciation of music. The styles of songs are diversified and the voices are recognizable. Although the vocal cord ability has also deteriorated, it is still much higher than Na Ying. Most singers who debuted with May at the same time were beaten to death by the new generation. Those who can hold their positions are either uninvited singers with excellent singing skills (Eason Chan) or people who are good at firing themselves (Han Hong).
To sum up, Na Ying's fame depends on the times, and May's fame depends on strength.
