Step 1: Wash the cucumber, cut it into finger-thick cucumber strips, and put it in a basin for later use. Remove seeds and pedicels from green and red peppers, wash and cut into strips, and cut ginger and garlic into large pieces.

step 2: put cucumber strips and pepper strips into a pot, add appropriate amount of salt, stir well, and marinate for at least 2 hours, so as to marinate out excess water, and squeeze out the water by hand.

Step 3: Pour a proper amount of soy sauce into the wok, pour it out, add oyster sauce, sugar, ginger slices and garlic slices, cook for 2 minutes, turn off the fire and let it cool, then pour in cucumber slices and stir well.

Step 4: Add appropriate amount of cooked oil and high-alcohol liquor, seal it, cover it, and put it in the refrigerator for half a day before taking it out.
