Once upon a time, there were three piggy brothers who wanted to build their own house.从前有三只小猪兄弟，要盖属于自己的房子。
The eldest built a thatched house, the second built a wooden house, and the third felt that the brick house was safe, so he built the brick house with difficulty.老大盖了草屋，老二建了木屋，老三觉得砖屋安全，艰难的建了砖屋。The wolf came and blew down the boss's hut first.大灰狼来了，先吹倒了老大的草屋。Then he collapsed the second man's wooden house, and the three brothers hid together in the third man's brick house.接着撞塌了老二的木屋，三兄弟一起躲在老三的砖屋。The brick house was so strong that the wolf had to give up his plan to eat pigs.砖屋很坚固，狼只好放弃吃小猪的计划。
