 If there were good weather on "Renri", it was considered that people will have a year of peace and prosperity.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".
