1. Try to make up an excuse to ask the bus company for the surveillance video of the bus, and see if you can get a picture of the woman.

Stay at the station where she got off. If her family lives nearby, the chances will be better.

Take that bus again, and you may meet it.

4. Take a selfie or post your experience of sleeping on that MM's lap to find someone online. In fact, she didn't respond when you slept in someone else's lap? ..........................................................................................................................................................

5, waiting for the fate of the next encounter in the vast sea of people.

To tell the truth, the chances of success of the above methods are slim. Good luck!
