Hyo Jin Moon is the oldest son of Sun Myung Moon and Hak Ja Han. He was head of Manhattan Center Studios for many years and was being groomed for a major leadership position in the Unification Church movement until his highly-publicized divorce from Nansook Hong.

Nansook Hong eventually wrote a book, In the Shadow of the Moons: My Life in the Reverend Sun Myung Moon's Family ISBN 0316348163, documenting how Hyo Jin Moon violently abused her, was unfaithful and was addicted to cocaine.
