My friend gave Dr. Yan's bird's nest. How about this brand of bird's nest?

Not bad. I checked. Dr. Yan has a traceability platform for China inspection of bird's nest. Each bottle has a bird's nest traceability code, which is a label issued by the Scientific Research Institute of China Inspection and Quarantine Bureau. Only the bird's nest that must be produced in full accordance with the national food label is known as the "bird's nest identity card" of an industry, so the quality is still guaranteed.
