The tent, with an interior more than one hundred feet long and wide, was beautifully furnished; but, its style did not match with the traditional style of Great Yu. In addition to the many rare ornaments, the most striking object was a purple-green cauldron in the middle of the tent. It measured ten feet tall, with eight breathing holes arranged in the positions of the Eight Trigrams along its lid, which were constantly drawing air and energy from the surroundings.
