This is the taste of grandma! My grandmother is a very smart, hardworking and strong woman. She knows everything in her mind! The food she makes is best to eat.

Wash the plums, use a knife to put seven or eight knives on the plums, put some salt in the bowl and then mix them by hand, marinate for half an hour... then rinse with water and drain, add the white vinegar to the bowl. Stir with sugar and put it in a clock for a while! (Plums want to pick the tough, sugar can be increased)
