《隋书·列传·卷四十六》
那里的人淫乱而多忌妒。妻子在外淫乱，如有人告诉她的丈夫，那丈夫就要杀掉妻子，杀了妻子又后悔，又一定杀掉那告诉他的人，因此，奸淫之事最终不被告发张扬。
其俗淫而妒，其妻外淫，人有告其夫者，夫辄杀妻，杀而后悔，必杀告者，由是奸淫之事终不发扬。
The people there are promiscuous and jealous. If a wife commits adultery outside, if someone tells her husband, the husband will kill his wife. After killing his wife, the husband regrets it and will definitely kill the person who told him. Therefore, adultery is finally not reported.
