There land fiefs were granted by lords or the monarch to knights, who were considered the 'vassals', who in return promised loyalty to the lord and provided military support during periods of war. In China, instead of a salary, each noble was given land by the Zhou ruler along with the people living on it who worked on the land and gave part of the produce they raised to the nobles as a tax.
This system involved lords granting lands to knights, who were considered vassals, in return for loyalty and military service. Similarly, in China, noble families received land and the labor of its inhabitants from the Zhou ruler, who collected taxes in the form of agricultural produce.
