As to the reason why the doors are so low, local residents hold several theories: to save on building materials, because fishing is a poor and difficult way to make a living; to protect against windblown sand from the seashore; and to suit the habits of fishermen, who are used to low doors aboard ships.
所以如此，當地居民有幾種說法：由於以打漁為生，生活貧困，建材能省則省；安平濱海，門開小一點，以防海風飛砂；漁民習慣於船上低矮的門。
