In the autumn of 2000, Zhang Xiaotian had not finished college, so he and his two roommates rented a small shop in the cultural and entertainment market to sell handicrafts. Just as the business was stabilizing, an ancient tomb was dug south of the market, revealing half of a dark blue stone door. The crowd of onlookers was so packed that Zhang Xiaotian leaned down between the iron sheets and took a look - this tomb was less than 200 meters away from his shop.
