A portiere was hanging in front of the door.

门前挂着一幅门帘.

Except that I like to open my room door for better air flow, so I need to buy a portiere for better privacy.

再加上我喜欢房间不关门通风，所以也得去买个门帘给自己一些隐私。

Suggestion: the owner in enough gauze portiere when see the intensity, because in the thickness of the profile has the very big difference.

建议：业主在选够纱门窗时看一下铝合金的强度，因为在型材厚度有很大的区别。
