How did ancient Chinese tombs set up mechanisms to deter tomb robbers? (This is just a basic demonstration - in reality, it was far more complex. The mausoleums of Qin Shi Huang (259-210 BCE) and Empress Wu Zetian (624-705 CE) remain unexcavated to this day because current technology cannot safely handle them.) Cnetizen say "No excavation needed - mercury level testing suffices. The Records of the Grand Historian documents that the First Emperor's underground palace used mercury to simulate rivers and seas. Being highly volatile, the mercury would have largely dissipated over time - not just since Xiang Yu's era 2,200 years ago, but even if Huang Chao's rebels had breached it 1,000 years later. Yet modern instruments detect severely elevated mercury levels at the site!" This confirms the mausoleum has never been substantially breached. While we cannot rule out that a few tomb raiders ('touching gold captains') may have entered, none could have survived - the instant mercury vapor exposure would have been fatal." Qin Shi Huang is revered as the 'Ancestral Dragon' in China, so people never joke about him - it’s believed to bring bad luck (a superstition tied to disrespecting the 'Dragon Emperor'). This might also explain why no one has dared to open his mausoleum to this day.

Ciò che il gregge odia di più è chi la pensa diversamente; non è tanto l'opinione in sé ma l'audacia di pensare da sé, qualcosa che non

sanno fare.
