Help finding a friend from Hong Kong

Hi. I'm trying to locate our family friend (who also happened to be our domestic helper) that we've lost contact with over the years. We last saw her in Hong Kong about 10 years ago and haven't heard from her since. We used to exchange Christmas Cards and the last time we were in HK her phone line had been disconnected.

As mentioned, she was our domestic helper (specifically from 1984-1993). She loved Chinese opera, had two sons, and used to live on Electric Road in Causeway Bay. The last time we met she had started working at a company (not sure which one), supposedly delivering mail, somewhere in TST.

Her name is Wong Lai Kuen (黃麗娟). I've attached a few photos below - two of them from the last time we met. She would now be in her mid-to-late 60's.

Hoping someone might have a connection - or be able to point me in the right direction of where to look.
