There are always two smells floating in the morning fog in Wuxi Village - the fragrance of the herbs picked by Lin Nianxi, and the sound of his brother Lin Yanqiu's unhealed cough. After his father passed away three years ago, Lin Yanqiu, who had just been admitted to a traditional Chinese medicine hospital, became the hope of his family. However, a serious illness caused by a heavy rain turned him from a quasi-doctor to a patient in need of care.
Lin Nianxi, who dropped out of school and followed an experienced medicine farmer to the mountains to collect herbs, carried her livelihood on her young shoulders. She traveled deep into the mountains to search for dendrobium and motherwort, exchanged wild ginseng for her brother's examination fee, and tied a peach rabbit around her wrist to pray for safety. The elder brother is working at his desk drawing an atlas of herbal medicine in an attempt to earn royalties, while the mother is working day and night weaving bamboo baskets to support the family. This family, trapped by illness and poverty, is filled with warmth in their mutual concern.
When the check-up list from the county hospital and the uncertain publishing opportunity are intertwined with the fragrance of medicine in the mountains, the sister's protection, the brother's guilt, and the family's perseverance unfold under the shade of the willows by the stream. This is a story hidden in the morning mist and the fragrance of medicine, about dependence in difficult situations, and about little people illuminating each other in the wind and rain.
