Have you ever heard of the Dragon Boat Festival?

Duanwu Festival, also known as Dragon Boat Festival and the Double Fifth, is a traditional and statutory holiday originating in China and associated with a number of East Asian and Southeast Asian societies. In Mandarin, it is known as Duānwǔ Jié; in Hong Kong and Macau, by the Cantonese name Tuen Ng Festival; in Hokkien-speaking areas, by the names Gō͘-go̍eh-cheh/Gō͘-ge̍h-choeh (五月節) and Gō͘-ji̍t-cheh/Gō͘-ji̍t-choeh (五日節). In 2008, it was recognised as a public holiday in mainland China for the first time since the 1940s.[1][2] The festival has also long been celebrated in Taiwan, Singapore, and Malaysia. Equivalent and related festivals in Asia include the Kodomo no hi in Japan, Dano in Korea, and Tết Đoan Ngọ in Vietnam.
