Create a poem with the theme of filial piety.

[Ancient Poetry]: The father of the Book of Songs is not filial; A brother who is not a friend is disrespectful; If the husband is unfair, the woman will be unhappy.

[Southern and Northern Dynasties] Yan Zhitui did not have a good father and brother in his life, nor did he have a strict teacher and friend outside, but few people succeeded. [Song] Lv Gongzhu

[Modern Poetry] The snow at his feet bears his footprints. The biting north wind whipped Strafe mercilessly, and his stubble eyebrows and beard turned silver with the cold wind. He continued to walk on the mountain road in Xiaoxing 'anling. I knew there was no road under his feet, and the goose feather-like snow drowned his footprints. Not far away, a string of broad shoulders and a bundle of chopped firewood were printed, and his tall and straight body inevitably bent down.

I will always love your father.
