The butterfly effect 

A meteorologist in the United States put forward a theory called the "Butterfly Effect." The effect is that a butterfly in the Amazon rain forest of South America flaps its wings several times. It may trigger a tornado storm in Texas America in a few weeks. This theory seems impassable, but the possibility can't be said not. Looking back, many historical events and natural phenomena in the global village are a series of "relations" and repeated occurrences; who can think of it? In 1914, the Crown Prince of the Austro-Hungarian Empire was assassinated and triggered the  WWⅠ, then the "Treaty of Versailles " signed after the end of the war became the trigger of the Chinese May 4th Movement and the WWⅡ. Soldiers and civilians killed and wounded in two wars, more than 100 million, it is terrible!

The 1958 revolution in Iraq is thousands of miles away from Taiwan, triggering the Quemoy Crisis (Kinmen 823 artillery combat). The photo below shows my father and his colleagues from a military exercise in southern Taiwan in 1957. Then he was assigned to the front line of the Quemoy (Kinmen) as a signalman next year, and I was only four years old then. God blessed him; fortunately, he returned safely after the war's end and is still healthy.
