Children and adults eat noodles on their birthdays. As for the custom of eating noodles on birthdays, it seems that it began in "The Queen of Tang Dynasty": "A Zhong takes off his purple arm and a bucket of noodles is a birthday soup cake." This Ah Zhong took off his clothes and changed his face in order to make birthday soup cakes. Why does he have to eat birthday soup cakes? Because in ancient times, boys were called "the joy of playing tricks" (Zhang: Baoyu's Book of Songs Xiaoyasgan: "Everyone is born with a bed to sleep in, clothes to wear and tricks." )。 In the Tang Dynasty, it was a custom to hold a soup-cake feast to celebrate the fun of playing tricks on Zhang. Liu Yuxi has a poem "A Gift to Jinshi Zhang Xi": "I remember my lonely days, and I was a guest. Toast to eat soup cakes and add Kirin. " Su Dongpo has "Happy Birthday": "I really want to be a soup cake customer, but I'm afraid I wrote Nongzhang wrong." Why do you want to be a "soup cake guest" in the Tang Dynasty?

Where's the soup cake? In Song Dynasty, Ma Yongqing thought in the book Lazy True Son that "those who must eat soup and cakes must want to live a long life." Noodles, at that time, have become a symbol of wishing the newborn boy a long life. This secularity has been handed down, and children and adults eat noodles on their birthdays.

Learning from the west, eating cakes and blowing out candles on birthdays first began in ancient Greece. In ancient Greece, people believed in themis, the goddess of the moon. At her annual birthday celebration, people always put honey cakes and many lighted candles on the altar to form a sacred atmosphere to show their special respect for the goddess of the moon. Later, with the passage of time, when the ancient Greeks celebrated their children's birthdays, they began to put cakes and other things on the table and light small candles on the cakes in the way of celebrating the birthday of Artemis, the goddess of the moon. Later, they gradually added a new activity-blowing out these lighted candles. The ancient Greeks believed that lighted candles had mysterious power. If the birthday child makes a wish in his heart and then blows out all the candles in one breath, then the child's good wish will surely come true. So lighting candles on the birthday cake and blowing out candles became a small program with auspicious significance at the birthday party, and gradually developed into an interesting activity of blowing out candles at birthday parties or banquets for children, adults and even the elderly.
