一言为定 is a Chinese idiom (chengyu) meaning “What is said is settled”. A promise is a promise, never to be revoked or broken. Literally, “one word settles it”.
Jia Lian, following the suggestions of You Erjie and You Sanjie, encountered Xue Pan and Liu Xianglian while on a business trip.
Jia Lian highly recommended You Sanjie to Liu Xianglian, and Xue Pan also advocated for strengthening family ties through marriage.
Liu Xianglian agreed to the marriage. Jia Lian said, '一言为定' (it's settled with one word), and proposed presenting a betrothal gift.
Liu Xianglian then entrusted Jia Lian with his ancestral treasured sword to take back.
