sentences:  Like the slaves, serfs, and indentured servants of the Western Hemisphere, "nobi" were considered property or chattel, and could be bought, sold, or gifted.The "nobi" were socially indistinct from freemen other than the ruling "yangban" class, and some possessed property rights, legal entities and civil rights.Hence, some scholars argue that it's inappropriate to call them "slaves", while some scholars describe them as serfs.
