Dad at the Stairs

He promised to take his father to climb Mount Tai, but his father suddenly suffered a stroke and became hemiplegic. He quit his job and carried his father on his back up the stairs in the community every day, from the first floor to the 18th floor and back down again. Neighbors said he was crazy, but he only said: "I am training." Three years later, he really carried his father on his back to the top of Mount Tai. His father sat on the top of the mountain and cried, saying, "Son, I'm dragging you down." He pointed at the sunrise and said, "Dad, look at the sun, it's the same as the one we saw at the top of the stairs, only it's bigger here." When he went down the mountain, he found that his cervical spondylosis was cured. It turned out that his father on his back was his best medicine.
