What are the similarities and differences between the feudal system in medieval Europe and the well field system in Western Zhou Dynasty?

Difference: Jing Tian is a slave system, while the fief system is a feudal system. Well-field system uses slaves, without any freedom, and fief system uses farmers, as long as they pay taxes.

Similarities: nobles enjoy a high degree of autonomy in their own mining areas and fiefs. They have all rights in their own territory except paying a certain tribute to the Lord and helping him fight. God won't interfere unless he resists.
