query: Do all males have to enlist in the Korean Aarmy?
passage: Conscription in South Korea
Conscription in South Korea has existed since 1957 and requires male citizens between the ages of 18 and 28 to perform in the army compulsory military service.[1][2] Women are not required to perform military service, but may voluntarily enlist.[3]
passage: People's Liberation Army
Technically, military service with the PLA is obligatory for all Chinese citizens. In practice, mandatory military service has not been implemented since 1949 as the People's Liberation Army has been able to recruit sufficient numbers voluntarily. All 18-year-old males have to register themselves with the government authorities, in a way similar to the Selective Service System of the United States. In practice, registering does not mean that the person doing so must join the People's Liberation Army.
