Renri

According to legend, the custom dates back to the Han dynasty, and gained importance after the Three Kingdoms period and Jin dynasty. Ancient Chinese had a tradition of wearing head ornaments called rensheng (人勝), which were made of ribbon or gold and represented humans. People also climbed mountains and composed poems. Emperors after the Tang dynasty granted ribbon rensheng to their subjects and held festivities with them. If there were good weather on Renri, it was considered that people will have a year of peace and prosperity.[1]

Fireworks and huapao (花炮) are lit, so Renri celebrates the "birthday" of fire as well.

Since the first days of Zhengyue are considered "birthdays" of different animals, Chinese people avoid killing the animals on their respective birthdays and punishing prisoners on Renri.

Nowadays during Zhengyue, Renri is celebrated as part of the Chinese New Year. Chinese people prepare lucky food in the new year, where the "seven vegetable soup" (七菜羹), "seven vegetable congee" (七菜粥) and "jidi congee" (及第粥) are specially prepared for Renri. Malaysian and Singaporean Chinese use the "seven-coloured raw fish" (七彩魚生) instead of the "seven vegetable soup".[4]

In Japan, Renri is called Jinjitsu (人日, jinjitsu). It is one of the five seasonal festivals (五節句, gosekku). It is celebrated on January 7. It is also known as Nanakusa no sekku (七草の節句, nanakusa no sekku), "the feast of seven herbs", from the custom of eating seven-herb kayu (七草粥, nanakusa-gayu) to ensure good health for the coming year.

The celebration of the feast in Japan was moved from the seventh day of the first lunar month to the seventh day of January during the Meiji period, when Japan adopted the Gregorian calendar.
