Are class II sleeper cabins air conditioned?
二级卧铺舱有空调吗？
Yes, most of them are. You can see if the class comes with aircon or fan when you book it. The aircon on trains or buses could be set to a temperature that would make a polar bear smile, so you better make sure to bring an extra jacket or your own blanket. You can also ask the train conductor for a blanket.
是的，大部分都有。你可以在预订时看看该舱位是否带有空调或风扇。火车或公共汽车上的空调温度可能会被调到让北极熊微笑的温度，所以你最好确保多带一件外套或自己的毯子。你也可以向列车员索要毯子。
