Ms. Lam Mei Iat and Mr. Si Tou Kuok Kuong, driven by the need to address family expenses and livelihood issues, serendipitously participated in the "Lunar New Year Firecracker, Fireworks, and Rocket Sales Event" organized by the Macau Civil Affairs Bureau (later renamed as the Civic and Municipal Affairs Bureau). They successfully bid for a temporary vendor stall for the event. This participation marked the beginning of what would become an annual family event during the Lunar New Year, a tradition that continues to this day. It was through this opportunity that we ventured into the industry of fireworks, firecrackers, and hazardous materials management.
