The next day during a break from work, the exiles all gathered around Pei Shu'er, asking about new ways to cook corn.
They knew Pei Shu'er was knowledgeable and clever; she had previously shared with everyone methods for cooking potatoes, cabbage, and greens.
"You can peel the corn kernels off and stir-fry them with a little oil. If you're too lazy to stir-fry, just boil and eat them, they're delicious too."
As for other ways to prepare corn kernels, it wasn't that she was keeping secrets; it was just too much trouble to make.
Everyone already didn't have enough time each day for farming, where would they find the time to sit by the mill and grind for hours?
She simply got tired of eating boiled corn and taught the people in the kitchen how to make it.
This way, if she wanted to eat it, she could have someone prepare it.

When Tang Zan went to the military camp, everyone curiously gathered around, wondering what new food he had brought this time.
