In the equal-field system in Sui, it was specified that a bare field of approx. 3.72 hectares and an inheritable field (segyoden) of approx. 0.93 hectares should be supplied to each male (the system to supply fields to wives, slaves and cattle was abolished).
隋の均田制では、男子に露田80畝と世業田20畝を支給することとされていた（夫人・奴婢・牛への支給は廃止されている）。
