mother seven years ago, I called the Diaoyu Islands
implant your name from my infancy
I walk back and forth in your warm embrace paradox
since I am no longer rootless plants

mother, a hundred years ago, I called the Diaoyu Islands
horse artillery
tear off the pride of my scars in your eyes I
scattered clouds sank
in those years,ladies plus clothing, you know
I need to rely on how much sway the heart

mother, I called the Diaoyu Islands
Sixty years ago you gently call my name
my delight but the robbers were in the sun
forcibly taken away the last moment of my virginity
moment, mother, you know I'm bent
shame to live in dire straits to torment

mother, thirty years ago I called the Diaoyu Islands
In my body on the robber from the runway repair
they want to rob me of all the enchanting
I should not have food on the table robbers
my cry, mother, you can hear the

mother, twenty years ago I called the Diaoyu Islands
in my body on the robber to the lighthouse shine
they want to forever hold my body I should not be a robber
shameless supper
I fragmented appearance, the mother, you can see

mother, I called the Diaoyu Islands
yesterday robbers knocked your kids and my fellow
robber funny excuse to give them shackled
They just to accompany my lonely Liao
why, why they use fire to burn robber

mother, I'm not the robber's mouth
Diaoyu Islands Senkaku Islands
I should not carrying a heavy backpack
chaos here on earth was I who laughed at the wonderful
should shine in your sky
broad and should be proud of my persistence in your warm embrace

mother I called the Diaoyu Islands
I look forward to,plus size coats, look forward to that second
Phi from your shirt, sounded the horn
fire in sharp
will call my name the moment, the mother lying
In your gentle arms, and I never want to care for your treasure
mother, I'm from the Diaoyu Islands
your name from the students called the old
