亁:
1. Same as "乾" (qián), which means "dry" or can refer to the sky or heavens.
2. (Verb) (Commonly written as 乹): A phonetic compound. The character is formed with the radical 乙, which represents the appearance of plants bending and growing. The original meaning is "to rise up." In the context of "乾," it also means "to rise up." — "Shuowen Jiezi"
3. (Noun) The first hexagram of the I Ching (Book of Changes); represents the sky. What reaches upwards is called "乾." Among all that rises, nothing is like qi (气), and heaven is the accumulation of qi, hence "乾" represents the heavens. — Zhu Junsheng, "Shuowen Tongxun Ding Sheng"
