What role did Chinese rulers play in promoting this golden age?

they made it possible

Explanation:

The Song dynasty (960-1279) follows the Tang (618-906) and the two together constitute what is often called "China's Golden Age." The use of paper money, the introduction of tea drinking, and the inventions of gunpowder, the compass, and printing all occur under the Song.

in the past, Chinese agriculture had been based on dry-land crops like wheat and barley. These crops grew well in the arid north, but not in the humid south. The south, however, was perfect for rice farming.

China's military ruled the empire during the Golden Age, and military leaders forced other countries into trade agreements. China had a policy during its Golden Age by which any man could become a merchant, and many took advantage of this policy.
