Sandi Village is situated northeast of Gyejok Mt., lower west of Seongjae and just south of the Apsan, and its name was derived from the old name of Sandui (behind the mountain) or Sanbuk (north of the montain) since it is a village at the rear of the Gyejok Mt. Since the northern valley of Gyejok Mt. is narrow and long, it is also referred to as Yeoldu (12) Sandi since it extends from the Gyejok Mt. in Jang-dong to Hayongho in Yongho-dong. This means that there are 12 villages in the valley at the back of the Gyejok Mt., the Sandi Village is situated at the foremost upper part of the Gyejok Mt. valley among them.
