Looking forward to the whole winter, finally, you come.

When I open my eyes, your shining figure is shaking in front of my window, and your crisp guttural voice is knocking on my window paper. How to put on your coat and push the door open urgently! I greet you.

Looking at you, my eyes can't shift for a moment; Listen to you, my eardrum never misses a syllable. From the distant horizon to the desolate plain, you struggle for life and death every minute. The joy of life, the fear of death, sings and shouts: Ding Ding Dong Dong.

I am really greedy, greedy to hold you and have you. So, I will smell you, smell you, and comfort you with my chapped lips. The anxiety of waiting for many days, when kissing you, is dull and moist.

Come on, dear you. Travel through time with me and see the young people who listened to the rain ten years ago. The West Lake in April, with yellow eyebrows falling, is colorful in the light blue sky and lake light.

That day, on Swallow Rock, I leaned against the "Red Chamber" and dreamed that the old capital of the Six Dynasties was rich in fat, fragrance and powder. You flatter me with the coolness of my cheeks. Do you really want to say goodbye? There is a basket of faint worries in the north carriage, which is from you. From Suzhou to Pennsylvania, only the radio said "Jianghuai" and "Huang Meiyu".

Ten years, I saw the scenery outside the Great Wall for ten years. The taste of the northland is only available when it is snowing heavily. White branches, white rocks, white glaciers and the arrogance and strength of Huguan Mountain are all among them. Northeasters like to build houses with red bricks, and there is a kind of glitz that is arrogant and not vulture in bright colors.

After living for ten years, I have never been used to it, so I have to hang a wind chime outside the window, visit Hanshan Temple in the soft Kunqu Opera at night, and think about the green mountains and green waters in my memory. Jiangnan likes blue bricks, always standing lightly in the fields, and occasionally rain drops on the tiles, giving off a gray tenderness.

Can wind chimes be the rain in my hometown? Can tonight's dream be the same as that of a teenager listening to the rain? Where does the warm current come from?

Come on, dear you! Give me a little southern flavor. I can't throw myself into her arms. It is a comfort to be swept away by her eyes.

Looking forward to more than 3,600 days, I still can't set a return date.

Looking forward to the whole winter, you fall from the clouds in your hometown and land on my hair tip, lips and heart?
