During the reign of Zhenzong of the Northern Song Dynasty, business opportunities and crises coexisted on the border after the Chanyuan Alliance. Bianjing businessman {Zhao Mingxuan} went to the border with great ambition to expand his business, but he repeatedly ran into obstacles because of his unfamiliarity with Liaoning, and even encountered difficulties from local ruffians. At the critical moment, {Xiao Yuechan}, the daughter of a wealthy businessman from the Liao Dynasty, stepped forward. She was proficient in bilingualism and familiar with the situation, and she took a fancy to Zhao Mingxuan's integrity and resourcefulness. The two decided to join forces to cross the borders of the two countries, transport Song brocade tea and porcelain to the Liao Dynasty, and transport Liao horse skins back to the Song Dynasty, creating a trade route amid language barriers and difficulties between officials and merchants. Just as business is booming, the main war faction of the Liao Dynasty wants to break the alliance and disrupt the border, and the shadow of war is approaching. They used business as their blade, and together with Han and Liao merchants, they wrote to the court to explain the benefits of trade and the harm of war, and finally protected the peace of the border and the peace of the people. This journey of joining hands in the business world and protecting their homeland also made the two of them fall in love gradually, and eventually became a cross-border love story on the border of Liao and Song Dynasties.
