At first, Li Lihua.

She was one of the big star at Shanghai and
Hong Kong.Without short time after WW2.
Always she was a top star .But now her image
is very little. I think cause she was always 2nd
But really she is a first singer who release LP
record in U.S.A . In 1957(maybe).

This recordis maybe first one which release
from major record company in U.S.A
U.S.A Capitol :T10087 "China!"
Capitol release many records about world music.

This is backside of the record.
and you understand
this one including another singer.

Tong Peipei was one of the famous star
between 1940's and 50's. Especially good for
Chinese folk song, and call Little Chow Hsuan.
Sorry but I don't Know about her well.
If you know more information ,please teach me
