三只小猪都知道大灰狼是坏蛋，都知道应该盖房子保护自己。可是，光有防备之心是不够的，还要了解大灰狼的能力，知道如何才能抵御大灰狼的进攻。前两只小猪不了解大灰狼，太轻敌了，所以吃了亏。如果都能像第三只小猪那样，认真地对待敌人，才有可能把敌人打败。

The three little pigs all know that the big wolf is a bad guy, and they all know that they should build a house to protect themselves. However, this is not enough, they also need to understand the ability of the big wolf and prepare seriously. The first two little pigs underestimated the enemy, only the third little pig did good preparation and defeated the enemy.
