I remember when I was a child, I didn't care to put chopsticks upright in my rice bowl. I have been scolded by my parents many times, and sometimes my parents will hit me on the head with chopsticks. Why? Later, I learned that when someone dies, a bowl of half-cooked rice will be placed in front of the coffin, and a pair of chopsticks will be placed vertically, commonly known as "pouring rice", which means that the deceased has finished all his rice. This custom has been preserved to show the memory of the dead, so people are particularly afraid to put chopsticks in their rice bowls. You can't do this at ordinary times, let alone on the festive and auspicious day of the Spring Festival. When I was a child, I often knocked on the bowl with chopsticks, but my parents didn't allow it. Who is knocking on the bowl? That's a beggar. Yes, you see beggars are always carrying a broken bowl, knocking and shouting: Come, give me a bite to eat.
