"Han Shi Tie" is a poem written by Su Shi, ink on plain paper, 34.2 cm in width, 18.9 cm in length, 17 lines of running script, 129 characters. It is now in the National Palace Museum in Taiwan.

I wrote two five-character poems for the Cold Food Festival in the third year of Huangzhou: "I have been here in Huangzhou for three years. I want to cherish spring every year, but I don't want to miss it. This year it rains bitterly, and the autumn is bleak for two months. I lie down listening to the begonia flowers and the mud. Yan Zhixue. I carried it secretly. I was really strong in the middle of the night. What a sick young man. The disease started to turn white."; "The spring river is about to enter the house, but the rain is coming. The hut is like a fishing boat, in the misty water clouds. The empty kitchen is cooking cold vegetables. , broke the stove and burned the wet reeds. I didn't know it was cold food, but I saw a crow holding a piece of paper. The king's gate is nine levels deep, and the tomb is thousands of miles away. I also want to cry that the journey is poor, and the ashes can't be blown away."
