No matter how old you get you can always learn new things. I learned something new already this morning.

The national holiday known as Taiwan National Day or Double Ten Day is observed in Taiwan every year on October 10. Nearly all Taiwanese have the day off from work. In mainland China, Double Ten Day is known as the Anniversary of the Wuchang Uprising, where commemorative ceremonies are conducted. In Taiwan, thousands of people flock to the capital to attend the large celebration parades in front of the presidential palace. Attending foreign diplomats and dignitaries sit alongside the president and view the people taking part. Events include military parades, dancing, music, and fireworks.
Taiwan National Day commemorates the beginning of the Wuchang Uprising in China on October 10, 1911. The revolution brought an end to the Ching (Qing) Dynasty, which the Manchus had created in 1644. The insurrection resulted in the establishment of the Republic of China on January 1, 1912.
Having lived in Tainan, Taiwan while in High School I continue to celebrate Double Ten day and support the defense of Taiwan.
