凉城之地必有凉薄之人
[liáng chéng zhī dì bì yŏu liáng bó zhī rén]
'In a Chilly City, There Must Be Cool-Hearted People' contrasts an environment or setting with the demeanor of people within it. It could imply that harsh environments lead to detached or unfeeling individuals but also possibly reflect on the inner strength needed to endure adversity.
