Guangdong's calling card holder is in Guangxi, but the health code was given to red team. Maybe it's because there is an epidemic in Guangdong where calling cards are handled, so I give a red team to everyone who has handled calling cards here. You can call the relevant staff and make it clear where you are and whether you have returned to Guangdong recently, so that the staff can cancel.
Red team said that the health code turned red, which should be green under normal circumstances. It is suggested that the epidemic situation in red team may be found locally.
