给出一些文字，要求模型进行语言风格和语法的校对，并提出修改建议。


“这个图书馆有六个房间，每个房间都有两张桌子和六把椅子。”
This library has six rooms, each of which contains two tables and six chairs. 

Modification suggestion: 
1. Use "contains" instead of "has" to avoid ambiguity. 
2. Add an article "the" before "six chairs" to specify which chairs are being referred to.
