After all, Mr. Yan's son was still young at this point, and couldn't think that far ahead.
When something like this happens, the first thing to do is find the police. In the exhibition hall there were lots of people in security uniforms, so he jogged in, spotted one, and told them that a little sister had gone missing.
The security guards all knew him. As soon as they heard a child was lost, they immediately tensed up, but they couldn't cause a commotion or alert the suspect, in case the "kidnapper" realized and ran off with the child.
They had people closely watch the entrance for anyone going in or out without a child, sent one team to inform Mr. Yan, and another to check the surveillance.
This was a jewelry exhibition, after all, with tons of cameras and almost no blind spots. Based on the place he said the "abduction" happened, they quickly locked onto that woman in a mask and cap.
