Can Shenzhen Longhua ask the driver to show his health code when taking a taxi?

Of course.

During the prevention and control of the situation, when the general public in the city take buses and taxis (including the network car), the bus safety officer or driver and the taxi (including the network car) driver should guide the passengers to show their "health code" on their own initiative. Those with "green code" can travel normally, while those with "yellow code" and "red code" should be discouraged from taking buses and taxis (including online car-sharing).

If the elderly and children fail to apply for the Health Code, it shall be implemented in accordance with the control regulations on taking buses and taxis (including online car rides) during the epidemic prevention and control period, and at the same time, do a good job in communication and explanation with passengers.
