Everything happened on an ordinary day. When Li Li was having breakfast and Dad was singing. "Four-color flag... red and black... green and white are forbidden! Just blue and white flags are allowed." But Li Li wanted their own four-color flag, their perennial poem under the flag and the labels on their belongings. So, she ran to Dad's watermelon garden, the red and black, green and white watermelon. Where everything was supposed to change... Maybe the watermelon could be a secret between them... Everything happens on ordinary days. When Tina sticks the watermelon label on the car window and when Dad rushes into the car... This time "From now on, watermelon is forbidden!" But the path ahead is never closed. Maybe Tina's four-color bag or...? This time, you tell the clue! This story is based on a true event. In 1967, in the land of Palestine, watermelon was banned!
