For Cai Jinglan and her husband, hope is to stay alive. Cai lives in a small village in the mountains. She'd been a migrant worker to support her family. Although it was arduous with low-income, she stayed calm and peaceful. That was before a decade ago when her husband was diagnosed with nephrotic syndrome. While she was in despair, the secretary of the village noticed the condition of the low-income family. He found Cai and suggested she apply for the housekeeper of the homestay hotel.
