Once an iron and steel giant in China, Shougang Group is restructuring its Beijing park from a steel factory into an innovative and environmentally friendly multi-functional inner-city park. Liu Boqiang, one of the 16,000 workers who have changed careers from first frontier factory workers to serve the 2022 Winter Olympics, has been working for Shougang Group for 22 years. Liu used to be a mill man at the factory but is now focusing on ice making, sweeping, and the maintenance of the four ice sports venues' rinks to ensure the daily training of China's national teams.
