《太平广记·卷九十三·异僧七》
出发之后，各位官人弟子都骑着官马，唯独长年一人徒步走路，因他从小到今，一直坚持修练苦行，从来不骑牲畜。
诸官人弟子等，并乘官马。唯长年一人，少小已来，精诚苦行，不乘杂畜。
After setting off, all the officers and disciples rode official horses, except for Changnian, who walked alone because he insisted on practicing asceticism since he was a child and never rode livestock.
