Chinese surnameChinese surnames are used by Han Chinese and Sinicized ethnic groups in China, Taiwan, Korea, Vietnam and among overseas Chinese communities around the world such as Singapore and Malaysia. Written Chinese names begin with surnames, unlike the Western tradition in which surnames are written last. Around 2,000 Han Chinese surnames are currently in use, but the great proportion of Han Chinese people use only a relatively small number of these surnames; 19 surnames are used by around half of the Han Chinese people, while 100 surnames are used by around 87% of the population.
VassalA vassal or liege subject is a person regarded as having a mutual obligation to a lord or monarch, in the context of the feudal system in medieval Europe. While the subordinate party is called a vassal, the dominant party is called a suzerain. The rights and obligations of a vassal are called vassalage, while the rights and obligations of a suzerain are called suzerainty. The obligations of a vassal often included military support by knights in exchange for certain privileges, usually including land held as a tenant or fief.
Vassal stateA vassal state is any state that has a mutual obligation to a superior state or empire, in a status similar to that of a vassal in the feudal system in medieval Europe. Vassal states were common among the empires of the Near East, dating back to the era of the Egyptian, Hittite and Mitanni conflict, as well as ancient China. The use of vassal states continued through the Middle Ages, with the last empire to use such states being the Ottoman Empire. The relationships between vassal rulers and empires was dependent on the policies and agreements of each empire.
