A tourist left her brand new phone on a shared bike in Nanjing, east China's Jiangsu Province – and the camera still worked even though the phone was locked.

When she got it back, there was a video message on it.

Now, she's posted the video online to track down the strangers who found it.

They insisted they want no reward. But the owner is intent on sending them some Hubei specialties as a thank-you.
