In the barren Loess Slope in the late 1970s, Qing He, a girl who was picked up, struggled to survive in a cold family background and heavy work. She was a "wild girl" who was bullied by the children in the village and ignored by her parents. Until the appearance of Chen Wangshu, an educated youth, illuminated her gloomy life like a beam of light.
Every evening, the wheat straw pile became a secret corner for the two of them. Chen Wangshu taught her how to read, read poems, and told stories about the city. He treated her gently and made a promise to return to the city to pick her up. Qinghe hid her heart full of joy and responded with roasted sweet potatoes, wild dates, and handmade cloth shoes. This pure love was the only sweetness in her miserable life.
The quota for returning to the city was approaching, but Chen Wangshu missed the deadline to save the Qinghe siblings who fell into the water, and his future was ruined. Two years later, the spot was regained, but he died in a landslide on the way back, and the agreement came to nothing.
Qinghe was forced to marry and was trapped in the yellow land for the rest of his life. As time goes by, things change and people change. Only the blood-stained book of poems and the broken moonlight in the wheat straw have become thoughts that can never be touched in her heart, hiding a young and deep love that was buried in the loess and died without a disease.
