Extreme things must be reversed, that is, when people or things develop to extremes, they will transform in the opposite direction. Bad to the end, good is coming. It inspires us to understand the situation correctly, and the more difficult it is, the more we should see the light.

When things go to extremes, they will develop in the opposite direction.

This is a very far-sighted thought in China's ancient philosophy. This philosophy may originate from the Book of Changes, because there are great changes from five to six in the Book of Changes.

This is a special concept. You should be wary of fortune tellers, any profession will change. In extreme cases, we must pay special attention, and we can avoid unexpected disasters if we are psychologically prepared. Therefore, it is a famous saying of Laozi in the Tao Te Ching, which means that there are blessings in disasters, and there are also disasters in the blessings.

Later generations often use this sentence to warn everyone not to think that they are blessed, but they must be careful of the disasters that follow. Later, there was an idiom-"A blessing in disguise is a blessing in disguise", which was probably a story written by Lao Tzu to warn people that "misfortune is a blessing to lean on, and misfortune is a refuge to hide".
