Volunteers try lifestyle in 'moon cabin'

Two months ago, postgraduate student Liu Hui traded in store-bought food for long days of picking vegetables, milling flour, and eating bugs.

"All ingredients needed to be handpicked and cooked fresh," Liu said. "Our everyday meals included tomatoes, green peppers, eggplants and worms."

The biomedicine student from Beihang University was among the first group of four volunteers, two men and two women, to spend 60 days in "Yuegong-1," or Lunar Palace, a simulated "space cabin" in Beijing.
