Do you need a tag on the line pulled by the tent at the scene of the epidemic?

Need. Organize all grid workers to set up tents, pull cordons, draw rice lines, post nucleic acid detection signs, set up a "one-meter line", set up an order line and post guidance signs to maintain order, so the lines pulled by tents at the epidemic site need to be marked. The epidemic point means that after the inflection point, the case curve continues to rise but the growth rate slows down, and then it reaches the highest point and begins to decline.
