Story:
Once upon a time, a woodcutter was returning home with a cart full of firewood on a hot day. He stopped at a teahouse.
After sitting down and having some tea, he heard shouts outside: "Oh no, fire! The firewood cart is on fire!"
The woodcutter immediately stood up, grabbed his teacup, and rushed out. He threw the water from his teacup onto the burning cart.
But it had no effect at all; the fire grew bigger and bigger, and finally, the cart turned to ashes.
