Ancient Chinese historical books have long recorded that crab juice can cure lacquer poisoning. According to Pharmacist Liu Xianting's works Guang Yang Zaji(Miscellaneous Records of Guang Yang), there was a young man in Taiping County, Anhui Province. On the night of his newly married date, he suddenly fell ill, his whole body became red and swollen, his itching became unbearable, his head became swollen like a bucket, his eyes became swollen and he could not open his eyes. His wife was extremely anxious, and several doctors were invited successively. All of them failed in diagnosis and treatment. Later, Cui mo' an, a famous Huizhou doctor, was invited to come and treat him. As soon as herbalist Cui mo' an entered the patient's home, a strong smell of lacquer came to his nostrils. He observed the patient, felt the pulse and asked for his feelings, then said decisively, "it's lacquer allergy!" He immediately ordered his family to move all the newly painted furniture in the room to the yard, fumigate the room with brick burned to red and vinegar, sterilize the room, pound several kgs of crabs to get juice and spread it all over his body. In less than two days, the swelling disappeared and he recovered.

Put a proper amount of clear water into the steamer and put the washed sea crabs into the steamer to cover the lid. Boil the water in the pan with a big fire. Turn off the fire about 15 minutes after the water is boiled. Place the sea crab on a plate, pour a little yellow wine, sugar, and vinegar into the ginger powder, and dip the crab meat into it before enjoy it.
