Cotton was a strategic reserve of the Great Zhou Dynasty and was very scarce under the control of the Imperial Court. Commoner merchants had a quota for selling and buying cotton. It was bitterly cold in the North. People could still think of some ways to get food, but they could not resolve the problem of cold-resistant cotton clothes.
The Di people liked to attack in autumn and winter, and their cotton clothes were also damaged.
Without warm and cold clothes, the soldiers would suffer even more.
The You army was clearly a tiger's army, but because their armor couldn't withstand the troops and their clothes could not withstand the cold, they became tigers with those claws pulled out.
After testing whether it was feasible to plant cotton in alkaline lands, Yu Youyao became serious. She found someone proficient in agriculture and specially went to Long Province to learn how to plant cotton.
