What kind of grain can't satiate your hunger? It merely comes down to whether it's tasty or not.
Thirty pounds of white flour can last for a month, while a hundred pounds of black flour could last for three. If you're careful, you can even have some left over, making it more popular than white flour.
However, people in positions like Cheng An are supposed to give gifts on holidays, and the best gift is top-grade white flour. It's pure white, delicate, respectable, and generous. Even though black flour is better, it doesn't present well.
Chen Ming naturally had to maintain his relationships, so he exchanged fifty pounds of quality flour with Feng Qingxue.
He was in charge of the grain store. Everyone was well aware of this, and every high-level leader would seek him out, just as they would with Cheng An.
