The page for Ru Chan seems to make a lot of leaps in connecting the character (unnamed-in-dialogue) simply called "Ru" in the credits of Aliens of London and "Mrs Chan" mentioned by Rita-Anne in Rise of the Cybermen when she shows concern about Ricky being involved with the Preachers.

"Don't pretend you don't know! You've been seen. Mrs Chan told me; driving about all helter-skelter in that van."

- Rita-Anne Smith

Is there anything which connects the brief role in Aliens with the surname "Chan", or is this just a ton of speculation?
