Preliminary summary:
Yan State's troops and horses were strong, and Xin State was defeated and negotiated peace, proposing marriage and trade. The Emperor of Xin State is young and his princess is not yet of marriageable age. He is willing to let the Prince of Yan State choose to canonize the princess and marry the State of Yan.
After the Emperor of the Xin State welcomed the four princes of the Yan State, he issued an order to summon the daughters of various high-ranking families in the Xin State to visit Duanlan Villa to enjoy the friendship between host and guest.
