烈酒烫喉清酒灼心
[liè jiŭ tàng hóu qīng jiŭ zhuó xīn]
It means 'strong liquor burns the throat, light alcohol scorches the heart', highlighting two contrasting aspects of drinking experiences - the physical intensity from strong spirits versus a metaphorical emotional intensity triggered by lighter alcoholic beverages, possibly hinting at complex emotions behind drinking, such as sorrow or contemplation.
