Kapitel 231: 231 It's a big deal.

```

Song Qinglong?

Song Xiaoyu and Song Xiaoxiao's dad?

Yan Yueqing's heart skipped a beat, this was getting serious.

Just then, Director Tang and Jiang Chuanning arrived.

Seeing Zeng Pao had come, Officer Chen and Officer Xu each questioned the two men separately.

Yan Yueqing took this opportunity to move to a secluded spot and made a call to Du Mansheng.

"Sister Mansheng, I want to ask you about something," she hesitated before speaking, "about Song Qinglong's business... How much do you know about it?"

"His business?" Du Mansheng didn't understand why Yan Yueqing was asking this but replied readily, "He mainly dealt in medical equipment. We started a business together back in the day, facilitating trade of medical equipment both domestically and internationally. We faced many ups and downs, but once things were on track, the income was decent."

"What about later? Were you fully involved throughout?"
