The second emperor of Qin Shi Huang, named Hu Hai (230 BC – 207 BC), was the eighteenth son of Qin Shi Huang. In 210 BC, Qin Shi Huang died, his eldest son Fusu was murdered, and Huhai succeeded to the throne by the second emperor of Qin.
Hu Hai was a ruthless ruler who took many political and cultural measures to consolidate his power. He abolished all the armies and government institutions established by the previous emperor and focused on building the Great Wall and unifying the six kingdoms. While this may seem like a beneficial move, the country's real financial situation has worsened because the potential of these institutions has not been fully realized.
Hu Hai also tried to maintain the mystery and unity of himself and his father Qin Shi Huang. He made gifts in gold for his birthday to show his glory and dignity. He ordered a massive search for gold and jewelry throughout China, where vast amounts of wealth were stolen by greedy officials and soldiers, leading to social instability and corruption in the military.
In the end, Hu Hai's rule was overthrown by a revolution, and Fusu's son Fu Wei staged a coup d'état. Hu Hai was forced to commit suicide, and Qin's dream of unifying the Six Kingdoms was shattered.
