The first drill on tackling emergency situations for the upcoming fourth China International Import Expo was held on Wednesday.

More than 500 personnel underwent training on how to be prepared for situations where a passenger who takes a bus to the site of the expo or a bus driver has high body temperatures or someone inside the expo venue tests positive for COVID-19.

Dozens of buses and taxis were involved in the drill. When a positive case is discovered, the close contacts of the infected person are also transported away.
