What does the first traffic stop mean?

It means: Traffic checkpoints, as the first point of entry for epidemic prevention and control, are the first line of defense against foreign imports. Traffic checkpoints are the frontline of epidemic prevention and control in our county and are crucial to coping with the current severe epidemic prevention and control situation. In order to control the first drop-off point and guard the entry point of external prevention, the parking lot strictly implements closed-loop management of people and vehicles, implements hierarchical and classified disposal, strengthens point-to-point transfer, effectively reduces the risk of epidemic import, and ensures that traffic checkpoints are safe, orderly, and smooth.
