Chinese surname, ginger
姜 centers on a Chinese surname and the plant ginger. The two meanings are separate; the surname is a proper noun, while ginger is a specific root used in cooking.
姜 is composed of 羊 (sheep) above 女 (woman). It is an ancient Chinese surname, possibly originating from a tribe associated with sheep herding. The ginger meaning is a later borrowing, unrelated to the character's structure.
A woman 女 under a sheep 羊: imagine a woman from the ancient Jiang clan, known for herding sheep. The ginger meaning is a separate borrowing, but you can picture her holding a ginger root.
For キョウ, imagine a woman named Kyou (キョウ) from the Jiang family, holding ginger: Kyou -> キョウ.
