Under the ground, the Beijing subway is working perfectly. Above the ground, workers from the countryside, the "Mingong", are working harder and harder to build the future of underground transportation.
To improve the subway transportation network and prepare Beijing's infrastructure for the Olympic Games, four new lines are to start operating by 2008. The total construction mileage of lines 4, 5, 9 and 10 is more than 100km, and the estimated total investment is nearly 500 million euros. As a result, Chinese banks have granted heavy loans to Beijing Subway Group to pay for the equipment and the construction of the lines.
