First, the girls of the Mengnu cannot undergo the "Daughter's Rites" within three years. Anyone who violates this will be punished according to national law, and those who mutilate their daughters will be punished with amputation of the hand.
Second, now that the Mengnu have surrendered to Great Jin, they will use copper coins and silver as currency henceforth, just like in Great Jin.
Third, the art of glassmaking is a unique technology of the Mengnu people, which must not be divulcted at will. The finished glass products shall not be sold to others either. Each month, a person dispatched by the Great Khan will purchase them in a unified manner. Those who violate this will be treated as traitors and punished by dismemberment by five horses.
Upon the promulgation of these laws, Cai Wei was very pleased. With the law as her assurance, her business development in these lands of Lingbei would go even more smoothly than before.
