Crab and tofu can be eaten together. Can not eat with crab are: persimmons and crab, persimmons are two things that can be eaten in the fall, but these two can not be eaten together.

Cannot drink strong tea: when eating crabs, the best drink is warm yellow wine, and it is best not to drink tea before or after eating crabs.
