Mother Zhang curiously asked about the train, wondering if it's very long, how it can still go fast, how many people it can hold, and whether it's faster than a car. She had never seen a train before and was very curious.
Zhang Guoqing explained to her one by one, trying to use simple language in his explanations.
"Mom, I'll take you to the provincial city to see a train sometime. When we visit my mother-in-law in Beijing, we'll take the train. But you have to know we can't take a sleeper, just seats. Can you handle three days?"
