《新唐书·列传·卷一百三十四》
蔡本赌输了几十万，拿不出钱来，来操就以蔡本的妻子抵债。其妻入来操家门时已怀身孕，以后生子即为俊臣，也就改姓为来。
本负博数十万不能偿，操因纳其妻，先已娠而生俊臣，冒其姓。
Cai Ben lost hundreds of thousands yuan in gambling and was unable to pay the money, so Lai Cong used Cai Ben's wife to pay off the debt. When his wife entered Lai Cong's house, she was already pregnant, and the child after birth was Junchen, so she changed her surname to Lai.
