Character recognition. The formal traceability code bird's nest label will be printed with the Chinese Academy of Inspection and Quarantine, and there is also the Bird's Nest Quality and Safety Technology Center below. If there are no or other words printed, it is a fake traceability code bird's nest.

Detail recognition. The formal traceability code bird's nest label has a light green, pink and blue background with regular geometric lines, and the logo and label are separable. If the color and texture of label shading, logo and label separation are inconsistent with the above description, it may be a forged traceability code bird's nest.
