Pedicab drivers use secret signals to outwit law enforcers (3)

"I used to take a pedicab home, but I don't like them as they're dangerous and uncomfortable. But people still need them, because the city still lacks transportation choices, especially between local transport hubs and residential compounds," he said.

Currently Hu's team has confiscated walkie-talkies and vehicles from three drivers. Although the vehicles will be returned, the walkie-talkies will be sent to the Beijing Radio Administration Bureau, said Hu.

"These drivers using walkie-talkies have violated the radio management regulations, so before the bureau makes a decision, these walkie-talkies will not be returned," Hu said.
