"That scavenger, was it a man or a woman?" Yan Junze asked.
"A woman." Grandpa Zheng answered while recalling.
Yan Junze thought for a moment, "Who else in the community might remember this incident?"
Grandpa Zheng wiped his mouth and pointed inside the community, saying, "Elder Pu living on the first floor of Building No. 4, I mean, I call him Elder Pu, but you should call him Old Master. He has lived here for a long time and might know something."

Yan Junze left the duty room and didn't immediately go home, but went straight to the building opposite his own, Building No. 5.
Elder Pu must be over 90 years old, hard of hearing, and after Yan Junze knocked, Elder Pu's daughter came to open the door.
Yes, his daughter is 64 years old, and Yan Junze calls her grandma.
Elder Pu was lying in bed because his legs and feet were not agile – he rarely got out of bed, and even if he did, he usually sat in a wheelchair.
