说到契约，记住，写得越详细越好，建材的项目、规格、数量、品牌等等都要写清楚喔，还有，千万不要忘记要求建商提供保固，虽然贵一点，但是比较有保障。

Talking of contracts, remember, the more detailed you write them the better and specify clearly things including the buildings materials, the specifications, the amounts, the brands and all that stuff. As well as that, whatever you do, don't forget to request that the construction company provides a warranty. Although it's a little expensive, it provides you with more of a safeguard.
