在爱彼迎上预定你需要知道以下信息：
What is the extenuating circumstances policy?
退改保障政策是什么？
Airbnb's reservations come with one of six cancellation policies set by the host, which range from flexible to super strict. These are set by the host.
爱彼迎的订单中包含房东定的6条取消条件中的一条，这些取消条件有的灵活，有的超级严格，都是房东定的。   
The company can override those conditions with its Extenuating Circumstances Policy, and that's how many Covid-19-related cancellations may qualify for refunds.
依据退改保障政策，公司可以不理会这些条件，所以很多受疫情影响而取消的订单才能全额退款。
When the Airbnb website recognizes that customers are traveling from or to certain affected areas, an automatic message is generated offering the chance to cancel without a penalty.
如果爱彼迎网站发现客户的出发地或目的地有疫情，就会自动生成一条信息，可以免费取消订单。
Even if travelers don't receive that automated message, they may still cancel their reservation and submit a request for a refund within 14 days of cancellation.
即使旅行者没有收到这条自动的信息，也可以取消订单并于14天内申请退款。
What areas are covered?
