in 2014, the system was upgraded to allocate the lower berth to passengers aged over 60 if there are spare tickets available.
2014年,该系统就经过升级,在车票有富裕的情况下,可将下铺车票分发给60岁以上的旅客。
similarly when we were taking a journey to xi'an, i found the lower berth was priced higher than the upper berth.
同样,在坐火车去西安时,下铺的票价也比上铺高。
the results show that airflow and temperature distributing are the best in the lower berth area, second in the hit berth, and the worst in the upper berth;
