Ka Sa Hyeob, who wrote 「Chea Mihn Yho Sul」, lived in the times of Book-Wi (A.D.386-535) and his birthplace was San-Dong Peninsula. If the Back-Jae dynasty governed San-Dong Peninsula during A.D. 285-500, Jeo(Kimchi) of 「Chea Mihn Yho Sul」 should be investigated as Back-Jae's Kimchi, beause it accorded with Ka Sa Hyeob's time of existence.
