Jiayi is a unisex given name of Chinese origin, derived from the characters "加 Yi" ( jiā yī ). It is pronounced as /dʒaː.i/ in pinyin, with the first syllable sounding like "jah" and the second like "ee". The name has no specific meaning attributed to it, as it is not a traditional Chinese name but rather a modern invention. Jiayi gained popularity in China during the latter half of the 20th century, particularly among parents who wished to give their children unique names that did not adhere to traditional naming conventions. Today, Jiayi remains a popular choice for parents seeking a distinctive name for their child.
"Jiayi experienced a notable rise in popularity between 2011 and 2019, with the highest number of births occurring in those years. However, there was a significant gap from 2020 to 2022 as no data is available during this period. The name resurfaced in 2023 but with a lower count."
