Hu also visited low-income families in eastern Beijing to inspect the operation of government-subsidized housing projects for needy people. He also inspected a heating plant in the eastern part of the city and encouraged its engineers and workers to work hard to guarantee the comfort of nearby residents throughout the winter.
