Xibei employees said they start preparing ingredients as early as 5am.

On the afternoon of September 12th, I visited several West Beijing locations to investigate. Some employees said, "It's quite unfair to say that our dishes are pre-made. How long does it take for these dishes to be served? Just cook them in water for a few minutes, then add scallion oil sauce and it's done. I don't think the process is as complicated as people think, so why do we need pre-made dishes?"
