Anna was very wary of people and he even kept a distance from the other village members. She did not have any friends around and the only person she could speak comfortably to was him.
The kids did not speak to strangers as well yet with this man who was a complete stranger, they were very warm and they were hugging him without any sign of fear!
Uncle Lu already knew who Anna was and he had chosen not to tell her because he wanted to keep her all to himself. With Anna's fame, there was no place that he could keep her without anyone noticing anything but this village was quite perfect because no one here knew her and the majority of the people were old anyway.
