What does the poem "Heart is inextricably linked, and eventually there will be a Qian Qian knot" mean?

The heart is like a double screen with a Qian Qian knot in it.

Song Zhang Xian's "Thousand Years"

The heart is like a net made of a pair of love threads, with thousands of knots in the middle.

[Appreciation] Words describe the depressed mood and unshakable faith when love is suppressed. "The heart is like a double screen with a Qian Qian knot in it." "Silk" is a homophonic pun, which means "thinking" of lovesickness. The two of them fell in love with each other, and there are thousands of knots tied with them, which tightly bind two hearts and two people's fate. This metaphor comes from life and is very vivid. Readers can imagine the depth and firmness of their love. Take the heart as the screen, contrast the lingering consolidation of love.

It is very enjoyable to describe the sad knot with double silk screens between the lines. Push the author's thoughts and feelings to the peak. The ending is lyrical, which connects the upper and lower films and has a long aftertaste. This word expresses the tragic beauty of classical love and makes people feel depressed.

[Original] Several times, it was reported to wheatgrass. Cherish the spring and break the red. The rain is small and the wind is fierce, and the plum blossoms are green. Yongfeng willow, no one flies all day. Don't pull strings, you can talk about it. The sky is not old, and the love is hard to break. The heart is like a double screen with a Qian Qian knot in it. The night has passed and the east window is not white.

[Extension] Qiong Yao's novel "Heart and Qian Qian Knot" not only quoted this word, but also made a poem based on this word:

The seas run dry and the rocks crumble, and feelings are hard to extinguish.

Seeing you, why don't you just leave?

Ask when the sky is old, ask when love dies,

I have a Qian Qian knot in my heart.

The meaning is endless, and the feelings are eager.

Intestines are inextricably linked into concentric knots.
