Story: Three little pigs grew up and left their parents to live by themselves. They each built a small house. The eldest built a straw house, the second a wooden house and the younger a brick house. After the house was built, they moved into their hut happily. But one day, a hungry and thirsty wolf came. He came to the big brother's house first and blew hard. Big brother's straw house was blown down, and big brother fled to his second brother's house. But the wolf blew hard again and the second brother's cabin was blown down. No way, the two brothers quickly fled to their younger brother's house. This time, no matter how the wolf blows, the brick house will not move. Later, the three little pigs used their brains to drive away the bad wolf. All three brothers gave thumbs up and said, "Brick houses are the strongest." ? On this day, the weather is fine, and the small fish in the river are swimming happily in the water. Hey! Why is the grass so busy over there? Small fish "Hua" jumped out of the water and looked at it. Oh, it turns out that three enthusiastic little pigs are helping the neighbor rabbit build the strongest new house! They moved wood, I moved bricks, and they did a great job! The small house will be built soon! There are many delicious foods on the stone table over there. It must be a hospitable rabbit to entertain the pig. ?
