縱（即容子用二反詩云從橫其畝韓詩傳曰南北曰從東西曰橫周禮九州之地域廣輪之數鄭玄輪從也廣橫也廣雅作從切韻唯作蹤縱䡮三字有作從不知所出也）。

Lengthwise (zong): (The two pronunciations are ji + rong [zōng] and zi + yong [zòng]. The Shijing says: "Lengthwise and crosswise are its furrows." Han's commentary on the Shijing says: "North-south is called zong; east-west is called heng." In the Zhouli, regarding the dimensions of broadness and wheel-length of the nine provinces, Zheng Xuan says: "Wheel means lengthwise; broadness means crosswise." The Guangya writes 从; the Qieyun only has the three characters 蹤, 縱, and 䡮. Some write 从, but its origin is unknown).
