PLEASE help me find this old tv show!!

Hi! I hope somebody here can help me because I can't remember enough about the series to know what it's called, or who is in it. I just know it was early/mid nineties.

The story centered around two young girls about 10 years of age (in the beginning), one poor (who sold flowers) and one rich. They meet and the rich family takes the poor girl into their home after her mother dies. They separate when the rich one moves to the States, and in a ***10 YEARS LATER*** kinda deal, the two reunite (the rich one sees the poor one singing on the street with a wig)

The only character name I know is the poor woman, Chiu Tong (Qiu Tong, Cheeyew Toung)...don't know how to spell it.

*SPOILER WARNING*
Eventually, the rich one gets married to an abusive rich man (and her father dies during this union) who she eventually murders and I think goes to jail briefly. The poor one gets with her boyfriend and they become fairly wealthy after building houses or something. Eventually the rich one ends up with the poor one's man and dies of cancer.

One subplot of the storyline is that a rich b*tch who is jealous of the poor woman makes chickens die on the poor woman's uncle's farm, so he commits suicide.

The last scene I believe is a kite-flying scene.

CAN ANYONE HELP ME WITH THIS AT ALL!!?? EVEN JUST ONE OF THE ACTOR'S NAMES?!
it would be GREATLY appreciated!
