In the Xi'an rescue station, when he learned that he could go home, the 82-year-old He Guili old man who has been wandering around for nearly 50 years lost his voice and cried. The old man said: my whole life, no one has ever hugged me, just that young man and those girls, they hugged me, so warm, really warm. I remember when I was a child, my mother rarely hugged me, my mother likes my sister, my father likes me, only my father likes to hug me.
