rise, raise
襄 centers on upward movement or lifting: rising up or raising something. The two given meanings are closely connected as the same action seen from different perspectives.
襄 is thought to combine 衣 (clothing) with a phonetic element that also suggests lifting or helping. The exact historical development is uncertain, but the character is associated with rising or raising.
Picture clothing (衣) being lifted up from a pile: the act of raising the garment captures the idea of rising or raising.
For ジョウ, imagine a person named Joe lifting a heavy robe: Joe -> ジョウ, and he raises it high.
