When purchasing tickets at 12306, some trains will be prompted with nucleic acid detection, requiring people who take these trains to enter the station with a green health code and a negative certificate of nucleic acid detection within 48 hours. Let's take Guangzhou, Zhengzhou and Nanjing as examples:
Guangzhou: Those who enter Guangzhou by car from middle and high risk areas need to provide health code, fill in health notice, make health inquiry and do nucleic acid testing, which requires 7 days of isolation and 7 days of home testing; Take a bus from the low-risk area to Guangzhou, as long as you provide the green code of health code and take your temperature.
Zhengzhou: Anyone who needs to take a bus to Zhengzhou Railway Station and Zhengzhou East Station must have a nucleic acid test report within 48 hours, and those who don't have it can't get on the high-speed train.
Nanjing: Take a bus from a low-risk area to Nanjing, you don't need a nucleic acid test certificate, just a green "Su Kang code"; If you take a bus from a high-risk area to Nanjing, you need a nucleic acid test report and a "Su Kang code" green code; Those who need to leave Nanjing by bus must hold the nucleic acid test report and the green "Su Kang code" within 48 hours.
