《魏书·列传·卷九十一》
人们首先商定一个婚嫁的时间，到时候男方建造车辆并将马匹拦起来，让女方任意挑选一匹马，不用马鞍骑上马走出圈马的围栏，马的主人则站在栏门之外，挥动双手来惊吓马匹，马惊而狂奔乱跳，如果骑在马上的人没有坠落下来，此马即被选中，若骑手落马，则换别的马匹，直到选满约定的数量为止。
结言既定，男党营车阑马，令女党恣取，上马袒乘出阑，马主立于阑外，振手惊马，不坠者即取之，坠则更取，数满乃止。
They first agreed on a time for marriage. At the appointed time, the man prepared carriages, penned horses and had the woman select a horse at will. The woman rode on the horse out of the pen without using saddles. The owner of the horse stood outside the pen gate and waved hands to frighten the horse, which ran wildly. If the rider did not fall off the horse, it was chosen. If the rider fell down, the man changed another horse until the number of horses agreed upon was selected.
