Today I went seoul museum of history.First I saw a Hopae.Hopae was an ID card.

On the front,there's the name,class and date of birth.The back has the date of issue.

People showed this to the gatekeeper before they entered the gate.

And I saw Umbilical cord jar.It is a special birth jar.The Umbilical cord of a prince or princess was put in this jar.People buried this jar along with a stone.The stone had the name and the date of the birth of the baby.

Thank you for listening.
