It was at the beginning of the reform and opening up in the 1980s, and many companies including Haier imported from abroad advanced refrigerator technologies and equipment. At the time, household appliances were in short supply, which led to many companies striving to expand in scale. Focus was put on quantity at the expense of quality. Instead of following this trend blindly Haier made quality a priority, putting into place a comprehensive quality management system. "Either not in it or in it for the win", as it was put. When finally there was an oversupply in the household appliance market Haier was already well positioned to win with its differentiated quality. During this period Haier was dedicated to making refrigerators, developing successful portable models in management, technologies, personnel, capital and corporate culture.
