It was already late in the evening, Baizhu was not waiting for patients and was going to go to rest. But before he could leave his office, he suddenly heard a timid knock on the door. A little surprised by the late visit, he got up and opened the door. What he saw made him even more surprised. There was a little boy standing on his doorstep, looking dirty and tired. He was all alone, there was no one near him.

"How can I help you?" Baizhu asked in a soft, kind voice, looking at the boy calmly and compassionately.
