arch, fold arms
拱 centers on the shape of an arch or the gesture of folding arms together, both suggesting a curved, enclosing form.
拱 combines 扌 (hand) with 共, which likely contributes both sound and the idea of joining or bringing together, as in folding hands into an arch.
The hand radical 扌 beside 共 suggests hands coming together to form an arch, like folding arms.
For キョウ, imagine folding your arms into an arch while saying 'kyou' (today) in Japanese: 今日 (きょう) -> キョウ, and your hands form the arch.
