rise up
昇 centers on upward movement: rising, ascending, or climbing. It describes things moving to a higher position or level.
昇 combines 日 (sun) with 升, which likely contributes the sound and the idea of rising. The sun rising upward is a natural image for ascent.
The sun 日 sits above 升, a shape associated with a measuring box or rising. Picture the sun rising up out of a box, climbing into the sky.
For ショウ, imagine the sun rising during a show: the show starts as the sun ascends, and show cues ショウ.
