Korean family trees include ties that are not by blood. Here is how to record adoption correctly.
A yangja is a son brought in from another household to continue the family line. The mirror term, chulgye, describes a person who leaves to continue a different household's line. This traditional succession kept a head family from dying out.
Modern legal adoption creates a new parent–child relationship in law, while foster care is a raising relationship. Distinguishing these keeps a lineage clear.
Traditional jokbo record an adopted person in both the birth and adoptive households, marking the one who left as "adopted-out" so the same person links across two families.
On JokboWorld you choose a relationship type — biological, adopted heir, adoption, foster, or adopted-out — for each parent–child link. Lines render solid or dashed by type, and you can jump between the same person in the birth and adoptive records.
Yangja is a son who comes "in" to continue a line; chulgye is going "out" to continue another line. They are the two sides of one adoption.
Yes. JokboWorld lets you pick biological, adoption, yangja, or foster as the relationship type, so modern adoptive families fit naturally.
