skill
倆 centers on practical ability: the skill or cleverness to accomplish something. It is a rare kanji for skill or talent.
倆 combines the person radical 亻 with 兩, which likely contributes the sound. The exact historical development is uncertain, but the structure suggests a person possessing a skill or talent.
A person 亻 beside 兩, which resembles a pair of scales or a balanced measure. Imagine a person skillfully balancing two things at once—that is the mark of real skill.
For リョウ, picture a skilled person named Ryo balancing two heavy objects: Ryo -> リョウ, and his skill keeps everything steady.
