Are people in Henan mainly pasta? I have two colleagues from Henan. I don't like it at ordinary times, and I eat very little in the factory.
The food provided by the factory for free must be rice, because it is only steamed. Northerners and southerners are different, and it is different to work and not to pay. Rice is just not hungry, and it will be hungry soon after eating it, so people who may contribute to their work are willing to eat steamed bread instead of rice, because they can only be hungry until after work.
