Song Yaoyao's fief was a commandery, and its name had long since been changed to Jiahe Commandery.
The commandery had four counties under its jurisdiction: Holy Pursuit County, Eternal Crossing County, Azure Luan County, and Falling Star County.
Holy Pursuit County had exceptionally high potato yields.
Song Yaoyao had Yuan Jibai buy up large quantities of the common people's surplus potatoes, then process them into potato chips, potato starch... and sell them.
Indeed, Song Yaoyao had people open a dozen or so workshops in Holy Pursuit County, hiring plenty of workers...
Now, not only did every household have enough to eat and warm clothes to wear, they had also saved up a fair amount of money.
That was how things stood in Holy Pursuit County, and the other counties were much the same.
Eternal Crossing County had exceptionally high sweet potato yields. Likewise, sweet potato workshops had been opened there, turning sweet potatoes into sweet potato starch, dried sweet potatoes... to sell.
Azure Luan County abounded in a certain kind of tree, which covered its mountains and fields. The trees bore fruit, but the fruit could not be eaten at all.
Song Yaoyao discovered that these were olives, which could be pressed for oil and had extremely high nutritional value.
Song Yaoyao then had people open oil presses in Azure Luan County. Once the olive oil was produced, it quickly took the entire Heavenly Phoenix Kingdom by storm.
Falling Star County's climate was suited to growing medicinal herbs, so Song Yaoyao specially sent people to teach the locals how to cultivate Chinese medicinal herbs...
After all these years, the people of the four counties were living in prosperity!
Many families had built spacious houses of gray brick with tiled roofs!
Song Yaoyao had another plan for this visit.
