Of course there are welfare homes in Korea. Welfare homes in Korea are classified in detail, including special welfare homes for the disabled, welfare homes for the elderly, various welfare homes for the disabled, orphanages and so on. I have never heard of a place where children have to be brought up by themselves, because in general, mothers in Korea bring up their children by themselves. If they take care of children, there may be a special nanny, and the fee is not clear. But after they are 3 years old, there are similar nurseries and kindergartens in China. The charge is not too high, but it is relative to the salary of Koreans.
