History
何以解憂 唯有杜康
“With what shall I dissolve this sorrow? There is only Du Kang — only wine.”
— Cao Cao曹操
ko무엇으로 이 시름을 풀 것인가 — 오직 두강(술)이 있을 뿐이다.
ja何をもってこの憂いを解こうか — ただ杜康（酒）があるのみだ。
The scene behind the words
The line that follows the famous sigh over life’s brevity in the Short Song; Du Kang is the legendary inventor of wine. But the "sorrow" here is no excuse for revelry — it is the thirst for talent not yet won, and the poem ends in imperial ambition. A millennium’s favorite drinking verse that is also, underneath, a conqueror’s sigh.
