What do you mean by flying independently?

Falling flowers are independent, swift flies two times "is a lonely poet, standing in court for a long time, facing the falling pieces;" I saw two swallows flying briskly in the drizzle. "Falling Flowers" and "Light Rain" were originally beautiful scenery, but in this word, they symbolize the exhaustion of fragrant springs and place their grief over the dead. Swallows fly in pairs, which embodies the independence of worrying people, thus causing an enduring spring hatred, and even after waking up from a dream, it is still melancholy. This kind of rhyme makes people linger. The phrase "falling flowers" is unique and constitutes a beautiful artistic conception.
