一笔朱砂倾城泪
[yī bĭ zhū shā qīng chéng lèi]
'A stroke of cinnabar ink shed by a city full of tears' is evocative of heartbreak and drama, possibly alluding to romantic tragedies or historical stories. The use of 'cinnabar,' a vibrant red mineral often linked with passion, contrasted with sadness suggests a deeply emotional story behind it.
