First, "look": the authentic Dong 'e Ejiao block has a flat surface, no bubbles, and a clear and tidy rubbing texture; Black as lacquer, light as amber, restrained and deep, with fine and moist texture.

two "smells": first, you breathe on the authentic Dong 'e Ejiao, then you smell it, it's a faint glue smell, and then you breathe on the fake Ejiao, and it's a foul and pungent smell that makes people sick.

three "tastes": authentic Dong 'e Ejiao Guyuan ointment, which has a faint fragrance when it is imported. The stronger it is chewed, the sweeter the aftertaste, which makes people want to eat it.

Now there is a verification code in each box of Ejiao, and you can also call to identify the authenticity.
