Hints:

exhaust fan

ventilation

Don't just call the police. That's what a lot of people do. So, that's a common complaint, loud music, but also sometimes we can have smells, or other things that disturb our senses. Yeah, that's a tough one, that's really a sensitive situation, because if you want to live in the comfort of your own home and not have to deal with unpleasant smells, then your neighbor is just as entitled to cook whatever she likes in the comfort of her own home. So, I would approach her, by saying, I am not sure if you realize what's happening, but, you know, I can smell something coming from your kitchen, would you mind opening your window or maybe using your exhaust fan. You try to approach them politely, reasonably, and if that doesn't work, you can also just talk to the management, and maybe there is something wrong with the building's ventilation system. If something is coming into your apartment, that might be a quick fix without having that uncomfortable conversation.
不要轻易报警， 很多人都选择报警。噪音问题的确很常见，但是有时我们也会遇到一些影响我们感官的的气味问题或者其他问题。 是的，这是个棘手的问题，确实有敏感性状况。因为如果你想在自己家里舒服地待着，不用遭遇难闻的气味，而你的邻居也有权在她家里做任何她想做的菜肴。所以，我会这么跟她说：“我不确定你是否注意到，但是我闻到你厨房好像有什么气味，你介意打开窗户，或者开启排风扇吗？” 你可以试着礼貌，且合理的方式告诉你的邻居，如果这样行不通的话，你也可以跟管理人员反映，也许是楼房的通风系统有问题。如果有什么气味窜到你的公寓里，作为权宜之计，这样就避免了一场不愉快的谈话。
