Put the vermicelli into the pot and add boiling water. After a while, filter the boiling water, cool it with cold water and cut it into pieces for later use. Wash the cabbage, cut it into pieces, put it in a basin, add a spoonful of salt and rub it repeatedly. Turn off the water. Put it in the vermicelli bowl. Put some onion and ginger into the pot, then add salt and chicken essence. Pour in a little oyster sauce and mix well, and the steamed stuffed bun with cabbage vermicelli will be ready.
