Who knows the story of small water droplets and big waves?

The small water droplets dripping from the cliff happened to drip on a hard stone, and it was determined to drip through the stone. This matter was known to the big waves in the river. The big waves laughed and said: Xiao Shuizhu said: "Hey! With your little strength, you can penetrate the rocks by the river. What a joke!" Xiao Shuizhu said: "If you don't believe it, let's compare. You can drill a hole in the rocks by the river. I'll drop this stone and see what the result will be after nine hundred and ninety-nine days." "Easy, easy!" Da Lang laughed, thinking that the small water droplets were pitifully small. Nine hundred and ninety-nine days would definitely not be enough. It can drop through the stone, and because of its great strength, it is easy to destroy the stone, let alone make a hole in the stone! Da Lang immediately agreed to compete with Xiao Shuizhu.

From then on, The small water droplets are aimed at a point on the stone, dripping, dripping, no matter it is windy or rainy, no matter day or night, they persevere and work hard. But the big waves are different. When they are happy, they will rush with a "wow", and they will not When you are happy, you are lazy...

Nine hundred and ninety-nine days have passed, and the small water droplets come to find the big wave: "Come and see, I have penetrated this stone, and the silver droplets have penetrated the stone." The small round hole still transmits light!"

When Da Lang heard this, he became anxious and quickly used all his strength to make "wow-wow-wow" sounds several times in a row, but the stones on the riverside still moved. Not moving either.
