The Gōa-káng-kháu-hiō（外港口滬, hiō: stone weir） of ng-nâ-tà-chng（紅羅村, chng: village） is a single pool stone weir, which located in the intertidal zone at the outer area of the ng-nâ-tà-hû-káng（紅羅漁港, hû-káng: harbor）. It is addressed as two different names by the locals. One is Sūn-kí-hiō （順己滬） which named after the offspring of the owner, the other name is Gōa-káng-kháu stone weir（外港口滬） with the literal meaning of “ the stone weir sat out of the harbor ”, in contrast with the Lāi-káng-kháu stone weir （內港口滬）on the right side with the literal meaning of “ the stone weir sat in the harbor ” which stands on the opposite direction of the fairway and also makes Gōa-káng-kháu stone weir（外港口滬） relatively further. - The Gōa-káng-kháu stone weir（外港口滬）and the Lāi-káng-kháu stone weir （內港口滬） of ng-nâ-tà village（紅羅村） are two stone weirs that linked by their dikes originally. Until 1993, the right dike of Gōa-káng-kháu stone weir（外港口滬）and the left dike of Lāi-káng-kháu stone weir （內港口滬） were amputated because of the harborage dredging construction of the ng-nâ-tà harbor（紅羅漁港）. - The isle.travel started the repair of Gōa-káng-kháu stone weir（外港口滬） with the stone weir repairmen team of ng-nâ-tà village（紅羅村） in 2018. On the advice of the repairmen ng Tsín-Khun, the team changed the direction of the amputated right dike and rebuilt a new right dike with new right weir tail in order to avoid intersecting the fairway of the ng-nâ-tà harbor（紅羅漁港）. By now, the pool, the right dike, and the right weir tail of the Gōa-káng-kháu stone weir（外港口滬） are completely repaired. Besides, we found Kúi-thâu-to'（鬼頭刀, 鱰魚, Coryphaena hippurus） in the stone weir during the patrolling on January 23rd, 2019.
