When Brother Hu came looking for him, Li Qing was playing some sneaky tricks with Wu Xingxing in the small shop.
He wasn't being sneaky about something. He was literally being sneaky.
The front of the counter could block the view of some people coming in, so they couldn't see what the two were doing behind it.
Li Qing took full advantage of this tiny blind spot in visibility, often seizing the opportunity to make a move.
When Brother Hu entered the door, Li Qing had just used a sharp knife to make Wu Xingxing a pair of crotchless pants. With a skirt covering the top, it was not only convenient for Li Qing to do whatever he wanted, but also basically impossible for people to see.
Winter had arrived, and everyone was wearing long pants, making these sneaky acts a lot less convenient.
