The title of this book is taken from Lin's famous poem "You are an April day on earth-a hymn of love" published in volume 1 (1April 5, 934). The original poem is:
I said you are April day on earth, [2]
Laughter lit up the wind in all directions,
Your soul dances in the glory of spring.
You are the cloud on the first day of April.
Breathing the soft wind at dusk
The stars twinkle with unconscious light.
The rain in Mao Mao sprinkled the flowers with joy.
That's light, that's elegant, and you are,
Lin
You wear a crown of flowers,
In your naive and serious way
You are the full moon every night.
When the snow melts, you look like a yellow gosling
You are as tender as a bud.
Gentle and happy
Water floats with white lotus in your dreams.
You are a blooming flower from tree to tree.
Swallows chirping on the beam.
You are love, warmth and hope.
You are the April day on earth! [3]
