There are six Shim clans in Korea based in the regions of Cheongsong, Pungsan, Samcheok, Buyu, Uiryeong, and Jeonju.
Fourteen percent of all Korean Shims are members of the Pungsan and Samcheok clans.
The circle was modeled on the Sun and the Moon, which symbolize that descendants will move forward, succeed, and be worthy of their ancestors.
It includes 10 volumes of genealogical tables, an index, and an introduction to the history of the Cheongsong Shim clan.
According to an officer of the Cheongsong Shim, they will eventually publish other genealogical tables on the internet.
