to stare straight ahead
睖 centers on a fixed, unwavering gaze: staring straight ahead with intensity or focus.
睖 combines 目 (eye) with 夌, which likely contributes the sound and may relate to a sense of rising or towering, suggesting an upward or fixed gaze. The exact historical development is uncertain.
The eye 目 on the left is fixed on the tall, towering shape 夌 on the right, like staring straight up at something imposing.
For チョウ, imagine a person named Chou who stares straight ahead without blinking: Chou -> チョウ, and his unbroken gaze matches the kanji's meaning.
