Huang Jie
Founder & Chairman
Founded Square Technology in 1986 as Nantong Refrigeration Equipment Factory.
Sifang’s journey has never been built on the efforts of one person alone, but on the shared dedication of generations of Sifang people. In an industry where competition is becoming more global, specialized, and demanding, we understand that lasting success comes not only from manufacturing capability, but from resilience, responsibility, and long-term thinking. As conditions improve, we must continue to carry forward the entrepreneurial spirit that shaped us: working hard, staying practical, serving customers with sincerity, and growing through every challenge. Looking ahead, we expect the new generation of Sifang people to take on greater responsibility, strengthen our capabilities, and help Sifang earn an even stronger reputation in the industry and across the world.
