Volumes 2 and 7 describe the Ming army attack on Luchuan, conflicts among the tusis, and the role of the Ming eunuchs (who prized the precious stones from the Ming-Burma border region) in Ming-Burmese border politics in the 15th century. These volumes also record briefly the manner in which the Ming envoys were greeted by the Ava king and how the Ava king and the Dai/Tai chieftains addressed themselves and the Ming emperor.
