She spoke to the Herald yesterday - sharing her and another close friend's memories.
"Xi was one of the most intelligent people in the world," she said.
"She was from China but studied at multiple universities around the world - that's how she ended up here.
"Xi was travelling and she decided she liked it, and she met someone."
That someone was Beazley.
The pair married, but separated while Wang was pregnant with their first child.
She was a single mother when the little boy was born.

"Her life was her child, she did absolutely everything - made every decision - for him," said her friend.
"She lived and breathed for her little boy.
"He absolutely adored her and he still asks for her, it's quite sad."
If anyone raised the subject, she would quickly change it.

"All I know is that she wanted to make the world a better place for her child … Ephraim was just someone that was outside the square," her friend said.
"Her focus was on her future rather than on the past."
According to her friends Wang was motivated, driven and fiercely independent.
She had become a New Zealand resident and was extremely excited about her future here with her son.
She taught him Mandarin, how to read and to play the piano.
She was proud of her appearance and was always perfectly groomed and styled.
"If there was something she wanted, nothing would stop her from doing it," said her friend.
"She was very sure, very adamant about her goals - she never let you down, she never broke a promise."
The friend said she was "shocked" and "baffled" when she heard Wang had died, and even more so when she heard who was allegedly responsible.
