And there's a reason for this: The Chiku region is the main producer of milkfish, and morning is when the newly caught fish are brought to market, and the fish stomachs are fresh; if the stomachs have been frozen and rethawed, they lose a lot of their original texture.
這麼千里跋涉是有道理的。七股一帶是虱目魚產地，早上正是活魚到市場的時候，魚肚還是新鮮的，要是魚肚凍過再解凍，質感就差了。
