Keeping the wheels turning at the Expo

SHANGHAI - As visitors rejoice in the festive atmosphere of the upcoming China Pavilion Day on Oct 1, Yang Yaoguo cannot do so.

As director of the electrical substation that powers the China Pavilion and the surrounding provincial pavilion complex, he understands his job is crucial to the pavilions being able to operate successfully.

To that end, he has been working round the clock at the electrical substation 15 meters beneath the China Pavilion, checking that if the facilities operate smoothly and carrying out maintenance and repair work when necessary.
