The information you provided is too little, let me make a guess~
Singles of this kind that appear on Chinese TV are usually Chinese singers; European and American songs are more likely to be English and Latin languages ??are less likely; the voice is very crisp, probably not pure bel canto, but folk beauty; almost screaming, the climax part is ahhhh and so on...
To sum up, My guess is "Glitter and Be Gay" (English name "Glitter and Be Gay", from Bernstein's musical "Candide") sung by Wu Bixia. Am I right?
As for the TV you saw, I guess:
1. If it is CCTV, it should be /v/b/22684012-1560053082.html
If this song is still No, that might be Wu Bixia's "Nightingale" (a famous Russian song)
/v/b/49541566-1258183707.html
In the last high note, she is not like many other coloratura women It's like going from bottom to top, but there is a gradual change in strength! The expression is so calm!
In addition, buy one and get N! The poster likes this type of music, so I’ll recommend some more, all by Edita Gruberova
