Why is a hundred-day baby called a hundred years old?

Due to the limited medical level in the old society, the infant mortality rate was very high within 100 days. If they can spend 100 days safely, they will have the hope of growth. "Hundred" has a complete symbolic meaning in the traditional cultural concept of our country, so the people pay special attention to the "hundred-year-old" day of babies and often celebrate it on this day, which is called "over 100 years old" and "walking for a hundred days". The custom of celebrating a baby's centenary became popular at least in the Song Dynasty. For example, Senator Meng of the Song Dynasty recorded in "Dream of Tokyo and Delivery": "A child born is called a hundred days, and the next birthday is called a week." It can be seen that "Hundred Days" and "Week" refer to ceremonial banquets held to celebrate babies' centenary and one year old respectively. Wu, a poet in the Song Dynasty, also said in Liang Lumeng: "A child will be born for a hundred days, that is, a hundred days, and a banquet will be held to celebrate." Since then, this custom has become popular. Hu Puan, a literary exegetist in the Republic of China, said in Jing Zhao: "After a hundred days, it is called the White Dew, and guests and friends are waiting for it, just like the full moon."

In the development of Chinese vocabulary, the shape and meaning of "Xi" (homophony with "Sui") were relatively vague and rough, and were later abandoned. Because in the centennial celebration of babies, "I wish children a long and healthy life" is the only theme; Therefore, it was later mistaken for "centenarians" by the people. 100 years old or older is another important etiquette in the baby's growth process except one year old. In this kind of etiquette, it also embodies the blessings and care of relatives and friends. These blessings and concerns are placed in their words, as well as in various symbolic foods, clothes and ornaments. This is how children grow up with the blessing and care of relatives and friends.
