Of course Zhang Huimei is the better singer.The difference between KTV level and the top level of the music pyramid. Na Ying is a typical white voice, poor breath, weak **** sound (basically no decent **** sound), vocal folds are not closed well, due to the lack of vocal training for a long time vocal folds have degenerated seriously. Advantage is that singing has a human touch, such as "Conquest" she sang very well; but because of this feature brings disadvantages is: she can not sing elegant songs. The most typical is and Faye Wong sang "about nine eight", the difference between Vienna and square dance (fun is also technically so big difference).
Na Ying's early years because she seized the rise of popular music and a song burst into the limelight, her popularity is entirely dependent on the turn of the times in the middle of a bullish song hit, and then so sat on the throne of the Diva and cold bench sitting to the present. Similar to her is Liu Huan, but Liu Huan's taste in music is much higher than Na Ying's (same personality).
HuiMei is technically much better than NaYing. The breath is stable, the ****ing is full, the strong closure of the vocal cords relying on closure to change the voice has been abandoned, and not only is the vocal range unified but also has a human flavor. Zhang Huimei's human taste and Na Ying is different, Na Ying's human taste is based on the basis of speech, Zhang Huimei's human taste is based on the basis of "vocal music", which is why Zhang Huimei's songs sound simple, but in fact, the reason is very difficult.
With her aboriginal background and the reasonable guidance of Zhang Yusheng, A-Mei not only has solid basic skills, but also has a good taste in music. Song style diversity, voice recognizable, although the ability of the vocal cords have also degraded but still a lot higher than Na Ying. Most of the singers who debuted at the same time as Zhang Huimei have been bloodied by the new generation, and the ones who can hold their positions are the ones who have excellent singing skills (Eason Chan) or are extremely good at firing their own people (Han Hong).
In summary, Na Ying's fame depends on the era, and Zhang Huimei's fame depends on strength.
