Chen ended up using duck along with the prescription, because in those days duck was cheaper than chicken, and also because of his mother's example (Tien's mother hailed from Changhua, a duck producing center, and always ate duck when convalescing after the birth of a child).
由於當時雞的價錢比鴨子貴，加上母親出身於盛產鴨子的彰化，從前也用鴨子坐月子，因此就用便宜的公鴨來燉煮中藥，沒想到竟然奇蹟似地康復了。
