Zhang Heng drove the van in pursuit of the tracker's signal.
Bai Qing was holding onto the car handle and finally asked a question that she wanted to ask for a long time, "When did you get your driver's license?"
"Oh, I don't have one," said Zhang Heng. "But it's okay, as long as I don't get caught by the police," he added after a pause.

Zhang Heng shortened the 40-minute journey to only about 20 minutes. He was, however, slowed down by a few traffic officers standing at several intersections along the way. About fifteen minutes ago, the tracker had stopped moving. Worried that Zhang Heng might track them down again, they should have headed to a different parking lot to swap cars.
After a while, the tracker hidden in the candy box started to move again and about ten minutes later, it stopped.
When she realized that the tracker had stopped moving, Bai Qing became really nervous. "Have we been found out?!"
