Oh, the other beautiful sight is the crimson hue of the beloved's love when he departs for foreign lands.

This beautiful couplet speaks of a love so deep, it's compared to a rich, reddish hue. It's the kind of intense affection a beloved carries, especially when they're embarking on a journey to a foreign land. Imagine a love so vibrant and strong, that even distance can't fade its brilliant color. This 'reddish color' symbolizes the warmth, passion, and enduring nature of their bond, a beautiful feeling that stays with them, no matter how far they travel. It truly is 'another beautiful thing' in life.
