Where ships sail through the sky

Yuan is deputy director of the engineering management department of Goupitan power plant. He said the conditions of the Wujiang waterway were poor before the dam was built because of its swift current. The water level from upstream to downstream can reach 199 meters over a long distance, and that makes things difficult for builders.

In addition, at the beginning of the project, as the power plant's generators needed to start spinning, engineers were required to generate power and build the aqueduct at the same time. Yuan always worried unconsciously about the danger of a slope collapse while working below the 230.5-meter-tall dam.
