In a beautiful village, there lived a mother pig and her three little piglets. One day, the mother pig let the three little pigs go out and build their own houses.
The boss was very lazy and built a house out of straw. The second child was not very diligent and built a simple house out of wood. Only the third child was hard-working and smart, and spent a lot of time and energy to build a solid house with bricks one by one.
Soon after, the big bad wolf came. It easily blew down the houses of the oldest and second oldest children, scaring them into running to the third oldest's house. The big bad wolf couldn't knock down Lao San's brick house, and finally left in despair. This story tells us that only through hard work can we gain true security and happiness.
