Father's Day is a day to express gratitude to one's father. Started around the beginning of the 20th century, originating in the United States, and now widely spread around the world, holiday dates vary by region. The most common date is the third Sunday of June each year.
In 1910, the world's first Father's Day was born in the United States, initiated by Mrs. Bruce Dodd. Mrs. Dodd's father, Mr. William Smart, took on the responsibility of raising and educating six children alone after his wife's death. After decades of hard work, the children finally grew up, but Mr. Smart passed away due to overwork. After attending the Mother's Day Thanksgiving service at the church, Mrs. Dodd deeply felt that her father's love and hardships in raising children were no less than those of any mother. Therefore, she hoped to have a special day to commemorate great fathers all over the world. On Father's Day, people choose specific flowers to express their respect and longing for their fathers. Wearing a red rose expresses love and affection for the living father, while wearing a white rose expresses mourning for the deceased father. The purpose of establishing "Father's Day on August 8th" during the Republic of China period was to commemorate the fathers who fought bravely and killed enemies in the war.

There is no official Father's Day in the People's Republic of China. But mainland Chinese people are accustomed to using the third Sunday of June as Father's Day; But in China before 1949 and in the current Taiwan, China region of China, Father's Day was on August 8.
