森旅的绿皮车
[sēn lǚ de lǜ pí chē]
This nickname evokes a nostalgic journey by an old-fashioned green train through the forest. The “green train” (绿皮车) in China refers to the older trains which have green carriages and evoke a sense of simplicity and slowness, often contrasting sharply with today’s faster travel. It symbolizes a relaxed and serene travel experience through nature.
