A Chinese girl used a clever way to ask for help while in custody. When a strange man was escorting the girl at an airport, she was not able to shout for help, showing a sign that resembled the word "OK" in English.
This was noted by one of the transients, who immediately began to talk to the man, and he and others soon realized that she was being held against her will; later to be reunited with her parents;
But turning your hand to face your palms is a meaningful message in China. If two fingers were pressed together, your hand would look like 110, the emergency police phone number of the Chinese police, so a passenger alerted that the girl was asking for help.
