A father bought a kite for his son. The son couldn't wait to fly it. So, on the next windy day, they took the kite to a park.
First, the father taught his son to fly the kite. Soon, the son was flying the kite high in the air. When it couldn't go higher, the son realized something. "The string (线) is holding the kite down," he said to himself. "If I cut it, it can fly higher."
The son cut the string. After that, the kite flew up a little more. However, the kite didn't rise for long. It slowly came down until it landed in a tree far away. The son was surprised.
"I thought the kite could fly higher without the string," he said. "What happened?"
"The string wasn't holding the kite down," said the father. "It was helping it stay higher. After you cut the string, it didn't have any support."
Really, rules are like the string that seems to hold us down in our daily life. But, without them, we can't fly high like the kite. We should never let go of them.
