The Guizhou QR health code system has become an effective and precise tool to help novel coronavirus epidemic prevention and the return to work, according to local officials.

Local officials said the QR health code system was put into use in Southwest China's Guizhou province on Feb 22 and as of March 1, the system had 110 million hits in total, with record daily visits of 20 million and a user satisfaction rate of 97.68 percent.

The health codes are categorized by purple, red, orange, yellow or green according to the health and travel information applicants give. As of March 1, there were more than 2.32 million applicants on the database.

Those who return to Guizhou from China's Central Hubei province -- a region previously hit hard by the epidemic -- with their health QR code displayed in red when quarantined, should immediately arrange for centralized isolation and observation for at least 14 days. The color yellow or green, meanwhile, as well as normal body temperatures means that people are healthy enough to move around the province.

The province has issued the promotion times, key areas and control measures for the system. In addition, a 24-hour help hotline – 9610096 --has been opened to handle the public advice and complaints, and the public satisfaction rate has reached over 96 percent, officials said.

Verification QR codes have been posted at the entrances of industrial parks, office buildings and project construction sites throughout the province to help the resumption of work and production.

Meanwhile, Guizhou has signed a memorandum of cooperation with Chongqing municipality to realize mutual recognition of the health code system through data sharing.
