"창사" refers to the founding or establishment of a company or organization. It is a significant event that marks the beginning of a business's journey, often celebrated with ceremonies or events. The term is commonly used in South Korea, where many companies highlight their 창사 to honor their history and achievements. In the context of South Korean culture, 창사 can also reflect the entrepreneurial spirit and innovation within the country. Many successful companies, such as 삼성 and LG, have their own 창사 dates, which are remembered and celebrated by employees and stakeholders as a way to foster a sense of identity and continuity.
