Blue in the Dark

Lyrics: Gu Yu Wu Chao

Music: Wu Chao

Throw away the cowardice in your heart and raise the gold The shield

The sacred national emblem above my head carries a sense of mission

Choose an ordinary and unknown dedication

I am always ready for the hardships and dangers of the future

Wrapped in blue in the dark night, holding a sword to support justice

When that helpless moan floats to my ears

Should I stand where I am or rush forward? Maybe there is an abyss ahead

But I saw the blue in the dark night

So I stopped staying, so I stopped wandering

Annotate it with my body The dignity of life

Rendering the police badge more vivid

So I no longer hesitate, so I no longer fear

Use your blood to cross the moment of life and death< /p>

Because I am the blue in the night
