在明代,政府根据财产和人丁的多少量定户的等级,并按照户的等级佥派徭役。在徭役的佥派上,国家规定了很多不服或少服徭役状况称为优免。而专业役户在承担了某种特定的徭役之后,对于一般性的民役是可以优免的,只是根据规定,不同的专业役户,优免额有所不同而已。 In the Ming Dynasty, the government decided on the level of households based on the amount of property and population and assigned military service at the level of households. In the military service, the state stipulates that many refuses to accept or less service status is called exemption. However, after a certain type of corvee has been undertaken by a professional servant, it is possible for the general civilian service to be exempted, but according to the regulations, different professional servants and special dispensaries will be different.
