1. It took me three days to watch "Butterfly Shadow Returns to Dust". Lin Die'er's life was like a colorful butterfly going through troubled times, with ups and downs. The last shot came to an end, and all the heartbeats, forbearance, and misses turned into dust. The most poignant thing in the book is never the separation between life and death, but the countless "almosts". 2. The ceiling of abusive writing during the Republic of China. There is no brainless nonsense, and the story of troubled times can't help but be written deeply into the bones. Three men have three kinds of love, paranoid possession, silent protection, and lifelong waiting, but no one can support Dieer for half her life. The butterfly shadow will eventually return to dust, and the lovesickness will never return. 3. The title of the book is the ending. No matter how dazzling the beauty, no matter how hot the love, they are as light as dust in the turbulent years. When I close the book, my heart is filled with emptiness. After all, the wind and moon in the world cannot keep a butterfly in troubled times. 4. Don't force perfection, don't deliberately sensationalize, and restrain your words to reveal heartbreak and regret. Die'er changed her identity and couldn't maintain any stability. It was only after reading that she understood that returning to dust was her only relief. 5. Yang Yanchen hid his gentleness for half his life, Xiao Qihao ruined his life with paranoia, and Zhang Zhiming waited all his life. All three people lost, but Dieer ended all the entanglements with his life. Dieying fell to earth, never to be seen again.
