The rivers were unhappy and angry. They had started out as tiny clear streams high up in the and ran through valleys（山谷）. The rivers had become wider and during heavy rainstorms and they had grown a lot.
But now， the end of their trip，they had to mix with the sea. They would lose valuable freedom forever.
However，they couldn't stop themselves from running，could they？So they had to keep till they reached the sea. "This is too unfair!" they said sadly to each other. "It's bad enough that we have to mix. It is worse that our sweet and drinkable water become terribly salty and awful we mix with the sea. "
The sea heard the rivers， "If that's the way you feel，I don't know why you should join me at all. Go ，and enjoy your cool，sweet waters by yourself. "
Of ，the rivers couldn't do that. Even if by some magic power they could change their way and not run into the sea，they were still about being in danger of getting lost. Because very few rivers lasted on their own without joining the sea. Most dried up and died. What use was independence if one did not live to enjoy it？
So the rivers made peace with their situation and got into the at last.
