### Chinese: 我是第一次到店只是给他们看了我的户型图，他们并没有去实地量过房子，他们居然就能给我报价说我的135的房子7万是可以搞定的，大概的给我看了一下他们的材料也并不知道他们是什么品牌的材料。
### English: It was the first time that I went to the store but I just showed them my floor plan. They didn't inspect the house on the spot and yet, they actually gave me a quotation saying that my 135 house could cost 70,000 yuan. I took a look at the materials and didn't know what brand they were.

### Improved English: When I first came to the store, I showed them my floor plan; although they didn’t really go to my apartment to take the measurement, they said they could do it within 70,000 for my 135 square meters apartment, and they showed me their materials whose brand was unclear.
