Of course you need a quilt. It's cold at night, and it's over ten degrees. Besides, you are a girl, and many girls don't bring quilts because they will come back from Shenzhen in three months. It's inconvenient to bring a quilt because it's too heavy. You can also buy it there. It only costs about eighty yuan. But the quality is average. (certainly not as good as your own home)
Or boys know how to save money and bring quilts.
