The store of "Hai Mama" is not large, but the six kinds of dumplings (dried scallop, soft thread, laver, sea unicorn, sea emerald, and vegetarian) developed by it are quite popular. This is mainly because the ingredients are fresh and combined with local ingredients, filled with the original flavor of the sea, which can definitely make customers feel the full freshness. Among them, the soft-thread health dumpling was rated as one of the top ten specialties in Keelung.
