《北史·本记·卷十二》
六年春正月初一为朔日。清晨，有强盗几十人，都头戴白冠，身穿白衣，焚香，手里拿着鲜花，自称是弥勒佛，从建国门进来，守门人都向他们低头敬拜。
六年春正月癸亥朔，旦，有盗数十人，皆素冠练衣，焚香持华，自称弥勒佛。入自建国门，监门者皆稽首。
On the first day of the first month of spring in the sixth year, it was the first day of the new moon. In the early morning, there were dozens of robbers, all wearing white crowns, white clothes, burning incense, and holding flowers in their hands. They called themselves Maitreya Buddha and came in from Jian'guo Gate. The guards all bowed their heads and worshipped them.
