Han Xiao was already chatting away with the old man.
Song Ning went over and asked a couple of questions too.
"Sir! This is clearly Changhui Street, so why does the address plaque still say Wenhua Street?"
"Oh! This factory originally belonged to the school. Only later was it put under the neighborhood administration. They opened a main gate on Changhui Street to make access easier, but the land still belongs to the school! That's why we still have to use the school's street address! Makes no difference! No difference!"
"Do people staying at the Guesthouse across the street ever come over here for a stroll?"
"Plenty of them! Not so many during the day, but come evening, lots of people go through our factory's side gate to walk around the school! There's a sports field there and plenty of trees. Everyone likes going!"
"And you... don't stop them?"
"Oh! This used to be the school's back entrance. We can't just seal it off! Besides, there's nothing valuable in our factory! Those machines are big and heavy, and the workshop doors are all locked at night!"
They chatted with the old man for a while before waving goodbye.

"Only Xu Changyi was attacked outright with a weapon.
