Starting from September 17th, passengers should use "Tianjin Digital Epidemic Prevention" App, Jinxinban App or Alipay "Health Code" APP to scan the 'venue code' on the buses and show the driver the scanned "green code".
"Passengers who hold their old-age cards, love cards, and children with adults are exempt from scanning the 'venue code', while other passengers who are unable to present the health code can register their information and get on the bus.”
