悲催！秦始皇屠杀了N9a母系近700,000人！

Ancient China's famous Terracotta Army was constructed by men bearing haplogroup N9a.
 
Qin Shi Huang, who unified warring states to become the First Emperor of China and founded the Qin Dynasty, ruled the Chinese state of Qin from 247 BC to 210 BC. In addition to his political feats, his reign is known for the massive construction projects, including his mausoleum in the Shaanxi province of central China, which began construction in 246 BC. To aid him in the afterlife, 8,000 perfectly life-like soldiers were crafted out of molds and clay and placed at guard over his tomb: his own Terracotta Army.

An estimated 700,000 workers were involved in the mausoleum construction alone, and in 2003, hundreds of skeletal remains were unearthed near the mausoleum. Curious about the ethnic origins of these men, a group of Chinese scientists decided to examine their mitochondrial DNA. They found that these workers had come from a variety of places across East Asia, and that the most common haplogroup was N9a.
