After the victory of the Anti-Japanese War, Shanghai gentry and celebrities all felt that it was meaningful to celebrate Father's Day! With active efforts, August 8 was designated by the then central government as the exclusive festival for dads. Since 2007, ASEAN has established August 8 every year as ASEAN Day. Since 2009, China has established August 8th every year as "National Fitness Day".
Extended data:
Father's Day is set on August 8 every year because "Dad" and "Dad" are homophonic, and the word "Dad" is connected like a "father" in the table. From then on, August 8th became the "Father's Day" in China. Why is it called China Men's Day? It may be decided according to the opinions of men who are not fathers!
But non-Chinese speaking areas can't play this kind of homophonic game. For example, Father's Day in Japan is the second Sunday in June every year. Father's Day in America, Canada and other countries is on the third Sunday in June.
