What is the line that best expresses the poet's longing for home in "Long Xiang Si"?

Noon good owner, the last line of the poem Dream soul not to Guanshan difficult. The last line of the poem, "Long Xiang Si", destroys the heart and liver.

Long Xiang Xiang Si, every time I think of each other, my heart and liver are destroyed!

Taking the sound and scene of autumn as a starting point, he writes about a man thinking about a woman. The beauty that I am thinking of is far away from Chang'an. It may be thought that this poem has a special meaning, which is the poet's nostalgia for Emperor Xuanzong of Tang after he was forced to leave Chang'an. Yu Shouzhen thought that "we can not say that he has a different meaning, completely chanted the 'long love affair' intention", there is a truth in this statement.

Thanks for your help
