How to cook cucumber as a side dish in the hotel?

Wash the cucumber first, pat it loose with a knife, and then cut it into four pieces. The length is up to you. Then evenly sprinkle fine salt on the cut cucumber, marinate for half an hour, pour out the drained water without washing, directly pour in aged vinegar (one third of the weight of cucumber) and appropriate amount of sugar, then add the cut red pepper (just for seasoning, but not too spicy), and cover and marinate for about three hours.
