This poem was written by Nan Zheng on his way to Chengdu via Jianmen Pass in Jiange, Sichuan.

He not only became the leader of the Southern Song Dynasty, but also enjoyed a lofty position in the literary history of China, with more than 9,300 poems, making him the poet with the most poems in the literary history. His poems have made outstanding achievements in both thought and art, although not as many as his poems, but they are also permeated with the spirit of patriotism. There are dozens of selected books handed down from generation to generation, such as Jiannan Poetry Draft, Weinan Anthology, Southern Tang Book, Notes of Laoxue Temple, Song of Weng, Weinan Anthology, etc.

No matter how poor you are, in our eyes, you are the richest; No matter how ordinary you are, in our hearts, you are better than any idol in the world!

It is the teacher who gives us a beacon to light up life and an oar to struggle on the sea of life.

I thank the passage of time for giving me the experience of growing up. I am grateful for the warmth and coldness of human feelings. I thank the ups and downs of nature for clearing my mind and the beauty and pain of life. Thank you bluebird flying across the sky, I am grateful to accompany you through this journey.

Jiang Nanyu stopped at Thanksgiving. Thanks to the clarity of the sea, I put on a blue coat for the sea. Because of the purity of the clouds, the sky is covered with a snow-white carpet. Thank the wind for blowing the earth green, thank the rain for watering everything, and thank you for bringing me a smile in my days.

The curtain that had been closed for a long time was opened and the light stimulated my eyes. I covered it with my hand, and you looked up at the window sill in a small gap between my fingers. Boring time begins to rush, loneliness begins to sing, lonely figure is expelled, life is full of your figure, where you are, there will be a smile.

Where there is you, there is hope. When life is no longer boring, when life finds its direction again, you leave me in a hurry and tell me to stand on my own feet and not to be sentimental easily. Life has a long way to go.

So, I know the days of gratitude, thank you, thank you every day of my life. 7. Thanksgiving Day again: The May wind in Meishan ironed out the wrinkles dried by mother. Children's blessings from all directions, such as the land of long drought, coincide with the spring rain. Moist laughter rose in the small courtyard of my hometown last year. Today, my sister's phone cry rumbled and faded away, and memory was like an opened floodgate. My mother's voice and smile are surging in my heart. Motherly love and kindness are the helmsman of vagrants. No matter how I go to the ends of the earth, my mother's words are priceless and sincere. Moonlight, dusk, dusk, touching my knees, dusk, before dawn, I worry about my mother. On this Thanksgiving Day, I can only mourn for you for countless minutes. Happy Mother's Day and Happy Thanksgiving. When all the mothers in the world are laughing, mom, are you okay in heaven? Have you ever heard of children's blessings and thoughts? I can only bless you deeply with words. 8.
