The Han Dynasty period in Chinese historiography is considered the golden age of the flourishing of art, politics and technology. The most significant technological breakthrough from this period is the seismograph. It is a device that records earthquakes, and the Chinese seismograph is a turning point in today's modern seismograph devices.
The first seismograph was two meters high. As part of the same, there were six sculptures of dragons that had balls in their mouths and six sculptures of frogs. When the ground tremors, the dragon drops the dragon from its mouth and rolls into the frog's mouth. In this way, depending on the direction in which the ball was going, the course of the earthquake was determined. So the Chinese knew what part of the empire needed help to be sent.
The biggest/most valuable products in the Han economy were iron, salt, copper work, and silk.
