Once upon a time, there was a poor hunter who only had a rudimentary bird gun and relied on hunting for a living. One day, he unexpectedly received a sum of money, and he used this money to buy a powerful cannon. From then on, he no longer had to hunt hard, and his living standard improved greatly. This story shows that sometimes, as long as the conditions change, great success can be achieved.
