You need a health code to take the high-speed rail. Before entering the high-speed rail station, passengers need to turn on their mobile phones to scan the QR code of high-speed railway station, show their health codes after logging in, or take out their mobile phones to find the latest health code pictures prepared in advance and show them to the staff in high-speed railway station. Only after the staff confirms that the passenger's health code is green will they be released and allowed to enter high-speed railway station.
If the passenger does not have a health code, or the health code he holds is yellow or red, he will not be able to enter high-speed railway station and travel as planned. To this end, passengers who need to take the high-speed train can first find their own health code on the mobile phone software and determine the color of the health code to avoid travel being affected.
Some people worry that the elderly or children don't have mobile phones and can't get health codes, which will affect high-speed rail travel. In fact, adults can handle parents' or children's health codes on the mobile phone software, and take screenshots of their health codes, and display them on the drawings or color-print them when taking the high-speed rail, which will not affect the problem of the elderly and children traveling by the high-speed rail.
