"What's the matter?" A uniformed train conductor hurried over to ask.
"Oh dear, Comrade Conductor, look at my old age; my legs aren't what they used to be. Climbing up and down is really inconvenient for me, so I thought of asking this young lady to exchange bunks with me." As soon as the elderly woman saw the conductor, she quickly put on an aggrieved expression and said, "But look at this young lady, just sitting there without saying a word, not considering other people at all."
The conductor glanced down at Tang Yuran, then looked up at the elderly woman and casually said, "There are plenty of lower bunks available in this carriage. If you want a lower bunk, just pay the difference, and I can arrange one for you."
"Pay the difference? How much would that cost?" the elderly woman asked in surprise.
"Fifty yuan," the conductor replied nonchalantly, glancing at the elderly woman.
