Throughout Chinese history, it has been a common cultural practice for families to assign infants nicknames in addition to their formal names. These nicknames often contrast sharply with Western naming conventions, as they are intentionally chosen to sound humble, plain, or occasionally vulgar. Common examples include animal-inspired names like 'Dog' or 'Pig.'

The primary motivation behind this tradition was rooted in superstition and the desire to protect the child. Parents believed that by giving a child a name that sounded insignificant or unappealing, they could ward off malevolent spirits or bad luck. The logic was that if a child appeared unimportant or 'lowly' to the spiritual world, they would be less likely to attract negative attention or misfortune, thereby ensuring their health and longevity. While modern naming practices in China have evolved, the historical context of these nicknames remains a recognized part of the country's cultural heritage.
