In the spring of 1976, cardiac surgeon Su Anran died during a heart surgery. When he opened his eyes, he returned to the time when he was eight years old. There is a crescent-shaped mark on her palm - it is the green and white jade pendant left to her by her grandfather. She held it for sixteen years in her previous life. Now the jade is gone, but the mark is still there. She didn't know if she was the only one in the world who came back. Until she met Lu Shiyan, a boy who never asked questions but said, "My grandfather also has a piece of jade."
Dandelions are sprouting in Sandaogou in the back mountain. Su Anran took her three children, Wen Xiaotang, Xia Qingqing and Zhou Yue, to collect herbs under the name "Grandpa Taught". The abandoned brick kiln is the stronghold, the drying cloth is the position, and a "Barefoot Doctor's Handbook" supports the whole spring. Lu Shiyan never asked her "how she knew", but just walked in front of her when she said "go that way". The two of them each had a piece of blue and white jade with a crescent pattern in their hands. Neither of them asked the other where the jade was, and both were waiting for the other to speak first.
From picking dandelions to collecting old things, from the back mountains to the provincial capital, they spent five years turning the regrets of their previous life into a steady flow of life in this life. The wormwood in the back mountain turns green every year, the door of the brick kiln is always unlocked, the road is still there, and the people waiting are also there.
