&quot;I&#x27;m sorry to know that there are people forced to live day by day in a high pollution environment though.&quot;<p>It&#x27;s funny, for &gt; 99.9% in Beijing, they have no reasonable way to escape, due to family ties, personal financial disruption from having to leave a job&#x2F;career, etc.  But there are many (not only foreigners) who could much more easily uproot and move to another city or another country.<p>The thing is, you go on hoping it&#x27;s going to get better over time, and pushing the decision further out, as &#x27;another few months&#x27; of this pollution isn&#x27;t going to make a serious health difference.
