The premier and the president took a group of children on a school trip.

“Look, children,” the president said, pointing ahead to a railway, where a long freight train was stopped on a single track, a line of cars stretching off in an enormous arc that bent around the foot of a hill with no end in sight.
“Wow, that’s a long train!” Huahua exclaimed.
The premier said, “Eleven trains in all, each with twenty cars.”

The president said, “At one gram of MSG and ten grams of salt per person per day, it’s a simple matter of arithmetic; those train cars hold sixty tons, and there are one-point-two billion people in the country. You do the math.”

Xiaomeng said, “But that is just salt and MSG. What about oil? And grain?”

“The oil would fill the pond over there. Grain would pile into the hills around us.”
