Clean the okra, remove the bad parts of the head and tail, put it in a steamer to mature (you can also cook it if you are in a hurry), let it cool, and divide it into two or four parts according to the size ( long bar), place evenly on the plate. While it's cooking, make the cold sauce (red oil, minced garlic, sweet and sour are all acceptable). 2 minutes before the meal starts (the water will come out if it is too early), pour the sauce evenly on the okra arranged on the plate, and then garnish with shredded green onions, celery leaves, etc., and it is delicious.
