carried out the King's official administration, as well as all military officers and officials of the Food, Music, Transportation, Agriculture, and other bureaus. Nanyue enacted several other policies that reflected Chinese dominance, such as the household registration system (an early form of census), as well as the promulgation of the use of Chinese characters among the Hundred Yue population and the use of Chinese weights and measures. Military Nanyue's army was largely composed of the several hundred thousand (up to 500,000) Qin Chinese troops that invaded during the Qin dynasty and their descendants. After the kingdom's founding in 204 BC, some Yue citizens also joined the army. Nanyue's military officers were known as General, General of the Left, Xiao ("Colonel"), Wei ("Captain"), etc., essentially identical to the Chinese system. The army had infantry, naval troops, and cavalry. Ethnic policy The Kingdom continued most of the Qin Commanderies' policies and practices dealing with the interactions between the local Yue and the Han immigrants, and Zhao Tuo proactively promoted a policy of assimilating the two cultures into each other. Although the Han were certainly dominant in holding leadership positions, the overwhelming disparity was largest immediately after the Qin conquest. Over time, the Yue gradually began holding more positions of authority in the government. Lü Jia, the last prime minister of the Kingdom, was a Yue citizen, and over 70 of his kinsmen served as officials in various parts of the government. In areas of particular "complexity", as they were called, Yue chieftains were often enfeoffed with great autonomy, such as in Xixu. Under the impetus of Zhao Tuo's leadership, Chinese immigrants were encouraged to adopt the customs of the Yue. Marriages between the Han Chinese and Yue became increasingly common throughout Nanyue's existence, and even occurred in the Zhao royal family. Many marriages between the Zhao royal family (who were Han Chinese) and the Lü family (Yue – they likely adopted Chinese names early in Nanyue's history) were recorded. Zhao Jiande, Nanyue's last king, was the son of previous king Zhao Yingqi and his Yue wife. Despite the dominating influence of the Chinese newcomers on the Hundred Yue, the amount of assimilation gradually increased over time. Language Other than Old Chinese which was used by Han settlers and government officials, native Nanyue people likely spoke Ancient Yue, a now extinct language. Some scholars suggest that they spoke a language related to the
