Zheng Minghui was stunned when he heard that Song Xiaojia was a police officer. After a long pause, he said, "Officer, I haven't done anything illegal. Why are you looking for me?"
Song Xiaojia smiled and said, "Zheng Minghui, don't overthink it. We're just here to ask you about some things, nothing else. Please have a seat."
Zheng Minghui sat down, looking at the three of them.
Song Xiaojia asked, "Zheng Minghui, did you go to Huainan Road around nine in the morning two weeks ago?"
Zheng Minghui thought for a moment and replied, "Yes, I went to Huainan Road that day."
"What were you doing there?" Xiao Xue asked quickly.
Zheng Minghui said, "That day, Technician Gong from our construction site asked me to post some letters for him at the mailbox on that street corner."
Upon hearing this, the three were visibly excited. Song Xiaojia then asked, "Do you remember what those letters looked like?"
