On May 3, 1767(43rd year of King Yeongjo's reign), 22 cargo vessels of Beopseongchang departed from Beopseongpo. Of them, 19 sank in the adjacent seas of Wi Island, Buan on the day of their departure. Only three managed to arrive at the Gyeong River. After the incident, 15,000 seoks of grain fell into water. Of them, 6,000 seoks were saved, but 9,000 seoks were not pull out and eventually lost. After judging that it was an unprecedented incident, King Yeongjo dispatched Seo Myeong-seon to the site as Honam Eosa. The investigation results show that the incident was caused by bad weather winds and huge waves that made it difficult to control the ships, but it was found that the ships broke the deadline and loaded private objects that had nothing to do with the transportation. As a result, Beopseongcheomsa and Yeonggwanggunsu received an actual prison sentence, but the Gamsaeks and Sageoks of each ship were found not guilty and released. In this process, King Yeongjo exercised his people-centric ruling philosophy.
