Explain the butterfly effect with examples, thank you!

From the perspective of "butterfly effect", Wu Song's personal behavior may have influenced the Song Dynasty and even the world history. This is just like in butterfly effect economics, economy and society are not machine-like operations, but more like living organisms.

in November of 159, Wu Erlang, who killed a tiger on Jingyanggang, was promoted by an exception. Wudutou was wandering in the street and met his long-lost brother Wu Dalang. As a sister-in-law, Pan Jinlian has a crush on brother in law, who is a "cadre" and is eight feet tall.

A few days later, when I went out to sell baked wheat cakes in Wu Dalang, a temptation spread out at home, but it didn't succeed. The righteous Wudu leader sternly refused and moved back to the county government to show his determination. Next, Pan Jinlian hooked Ximen Qing and poisoned Wu Dalang. Wudu's head was spattered with blood and Jiang Menshen was drunk. Then I walked the centipede ridge at night, met with timely rain Song Gongming, and decided to rebel together.

if Wu Song had followed pan Jinlian, what would the history of the great song dynasty be like? Let's spread the wings of imagination: first of all, it is difficult for Song Jiang to be recruited without Wu Song; Liangshan won't levy Fang La, and even if it does, there will be no one-armed Wu Song to capture Fang La.

If Fang La didn't die, Da Song might not attack Da Liao, Jin wouldn't rise, Mongolia wouldn't destroy Jin, and Song Dynasty wouldn't perish ... When Wu Song pushed Pan Jinlian away, he opened Pandora's box and knocked down the dominoes that rewritten the history of Da Song Dynasty!

however, the discovery of chaos effect in 1963 posed a great challenge to traditional economics: Lorenz, a scientist, published an article in Atmospheric Science, pointing out that there must be a connection between the inability of climate to repeat itself accurately and the powerlessness of long-term weather forecasters, that is, the connection between aperiodicity and unpredictability. He also discovered that chaos is "extremely sensitive to initial conditions".

This can be vividly compared with the "butterfly effect": theoretically, when a butterfly in Brazil flaps its wings, this disturbance will make a great difference in another place far away, which will make long-term prediction impossible, and even be amplified by the system into a storm in Africa thousands of kilometers away.

The "butterfly effect" on the tip of China people's tongue:

The British media said that the middle class in China was keen to buy American pork, which caused the residents near the pig farms in North Carolina, USA to complain bitterly, because the increase of pigs brought the problem of pig manure odor.

It's also reported by British media: China has drastically reduced its milk imports, and there is a global milk surplus, and the international milk price has dropped to a six-year low.

Just flip through, and there are countless such news: such as "China demand pushes up Japanese fruit price" and "China demand pushes up Malaysian bird's nest price". The "storm" caused by the tip of the tongue is just the tip of the iceberg. Due to the unexpected selling of several tons of gold bars in China market, the price of gold plummeted. There are also American media "complaining": "The slowdown in demand in China has made the US coal industry worse."

In a word, China's demand is as powerful as the "butterfly effect" in the global market.
