Problem {3}

Qiao Xin seemed to yawn a few times, and she kept yawning even after getting off the bus. At this stop, which was the last stop for passengers to drop off, Qiao Xin and Mei finally parted ways because their residences were in opposite directions. Mei glanced at Qiao Xin, who looked tired, making Mei smile faintly.

"Hey!" Mei said, patting Qiao Xin on the shoulder until her best friend turned to her. "Don't sleepwalk, okay. You have to get home before you sleep. I know your bad habit, Qiao Xin. You will sometimes look for a place anywhere as long as you can sleep. Remember you are a woman, and it's not safe here. I'm afraid that some masher will take advantage of you."

Qiao Xin waved her hand. Her eyes seemed to feel so heavy and almost closed tightly. She nodded slowly, then walked towards the Han family's residence, which still took quite a while.
