Sent a text trying to trick you into conversation and further down scam action.

"Hi! I'm yuqin, a friend of sister zhang. this is my first time in australia. sister zhang said you're really great and that i can ask you anything if i have any questions. Please take care of me in the future."

Did not reply to it, and then sent another message "Did you get the message? Please reply if you did, thanks!"

Beware of these kind of message, scammers often pose as a friendly, lost individual (like "Yuqin") to trick you into engaging in conversation, aiming to gain your trust and later move you to a different app to scam you financially.
