According to her bio

Alison Chang Yen was born in 1946 and a native of Chaoshan in Guangdong Province. She was still schooling at an English college when she joined Shaw Brothers at age 15

So I will split them from 1950 to 1960 if nobody stops me in 15 days.

Maybe she is the same as 17 but I am not sure so I will not merge them.
