《资治通鉴·后晋纪·后晋纪三》
南唐主便命有关部门考核二王的后裔，因为吴王的孙子李在历史上有戍守边疆之功，李的儿子李岘又当过宰相，于是以吴王为祖。说是从李岘之后，经过五世而至于南唐主之父李荣。
唐主命有司考二王苗裔，以吴王孙祎有功，祎子岘为宰相，遂祖吴王，云自岘五世至父荣。
The Lord of the Southern Tang had the relevant departments assess the descendants of the two kings, because Wu's grandson, Li, had merit in guarding the frontiers in history, and Li's son, Li Xian, had also served as the prime minister, so they used Wu as the ancestor. They claimed that from Li Xian onwards, after five generations they came to Li Rong, the father of the Lord of the Southern Tang.
