Should I take a bus if there is red under Hebei health code for 6 days and negative?

Does the subject want to ask, "can I take the bus if there is red or negative in Hebei health code for 6 days?" You can't. Hebei health code is an electronic health certificate for personal travel during the epidemic period, which is developed by using the information related to epidemic prevention and health in Hebei Province and the self-declaration information of residents' personal health. It's red for six days, which means you haven't done nucleic acid for six consecutive days. According to the local epidemic policy, you can't take the bus. You need to make nucleic acid until it turns green.
