Border police in Heilongjiang adopt a grandma

"For the new officers at the station, the first task after arrival is to visit Yu's home," said Zhao Jinghui, deputy director of the station. "In 2017, the station moved to the county seat 17 kilometers away, but we never stop helping the family."

Yu is grateful and calls the officers her sons: "We keep in touch even after they leave. I was really happy that every few days I received gifts and calls."
