Li Meixiang stepped forward and took out her key to try it, but just like Yang Lisheng, her key couldn't fit in, "Could it be that the lock core has been changed?"
Yang Lisheng carefully compared the lock core and nodded, "It seems it has been changed. I'll go ask next door."
Upon arriving at the neighbor's, Yang Lisheng raised his hand and knocked on the door. They hadn't come back for nearly ten years, and he didn't know if the person living there was still the previous old neighbor.
"Coming!" A frail voice came from the yard.
In a moment, the door creaked open.
An old man about the same age as Yang Lisheng came out. Upon seeing Yang Lisheng, he was stunned for a moment, then his face broke into a smile of surprise, "Are you Dr. Yang? Are you back?" It had been many years since he last saw Dr. Yang. When Dr. Yang and his wife used to live here, he'd go to Dr. Yang for every headache and fever.
