Why did Changchun Express stop again?

Today's epidemic:

From 0: 00 to 24: 00 on June/KLOC-0, there were no new confirmed cases and asymptomatic infection cases in Changchun.

Remind the general public that zero growth does not mean zero risk. We should continue to tighten the string of epidemic prevention and control, earnestly enhance the awareness of protection, comply with the requirements of prevention and control, cooperate with epidemic prevention management, and be the first responsible person for our own health. It is necessary to pay close attention to the dynamic information of epidemic situation released by various places. If there is an intersection with the activity track of the positive infected person, or if there is a recent living history in the epidemic area, please immediately report to the community (village) or the CDC, and cooperate with relevant epidemic control measures as required.

If you have acute respiratory symptoms such as fever and cough, please go to the fever clinic of designated medical institutions in time under the condition of personal protection. Vaccination with COVID-19 vaccine is an effective measure to prevent COVID-19. Please take the initiative to vaccinate as soon as possible, and insist on wearing a mask, washing hands frequently, ventilating frequently, keeping social distance, not having dinner or getting together, so as to reduce the risk of disease infection.
