In the old city where the morning fog has not yet dispersed, the first wisp of smoke drifted out from the newly opened "Lin Ji Porridge Shop" at the entrance of Qingzhuan Alley. Lin Yankang, a middle-aged widower who lost his wife, left Guangdong with his fourteen-year-old daughter Lin Yuexi, trying to smooth out the wrinkles of life with a bowl of warm casserole porridge in a small northern town.
In the backyard of the old house they rented in the Shen family alley, wild roses that had not been taken care of climbed over the low wall and formed a purple wave with the nameless wild flowers in the back hill.
Lin Yuexi met the high-spirited boy Lu Yuanzhou under the ginkgo tree in the back mountain.
