How did the Zhou dynasty use feudalism to rule ancient China?

The king treated landowners well and sent non-landowners to work on forced-labor projects.
The king gave land grants to peasants who fought in the military, which upset the noble landowners.
The king allowed nobles to use the land, and nobles used peasants to farm the land in exchange for protection.
The king made laws based on whether people were nobles or peasants, and laws were stricter for peasants.
