During the Han dynasty (206BCE-220CE), the Chinese invented (or improved) porcelain, water-powered mills, modern horse collars and breast straps, double-acting piston bellows, tube seed drills, ships with water-tight compartments and -last but not least- alcohol. It was one of the most important technological eras in recorded history. Some of those inventions were “re-invented” later in Europe. Pictured above is a government seal of the time period. It’s made of Jade and it’s a turtle.
