Dead Sea

An English writer once said that action may not always bring happiness, but inaction will surely never bring happiness.
In Palestine, there is a sea called the Galilee Sea, where many fish swim. The sea is surrounded by green trees and beautiful houses, making it a popular tourist destination. People living in the area have high income.
On the other hand, there is a sea called the Dead Sea, where there are no fish, trees, or houses on the sea side. Both seas originally received their water from a high mountain in Iran, and the water was clean and fresh.
However, when the water reached the Galilee Sea, it remained clean and continued to flow, but when it reached the Dead Sea, it became dirty and bad-smelling. As a result, the Galilee Sea's water never stops flowing and continues on and on, while the water in the Dead Sea goes nowhere, earning it the name "dead sea".
