reduced the company’s debt-capital ratio from 187 percent to 33 percent, and added as much

as 24 billion yuan to Zhang’s fortune, making her the wealthiest self-made woman in the

world.”My sister hates lazy people the most. She is always energetic and more diligent than

any other person I know,” says Zhang Yin’s sister Zhang Xiubo. “We obey her

business, but Zhang denies kinship plays a key part in her management.”Out of the whole

family, only one brother has entered the company’s management. I chose him for his ability,”

she said. “My husband used to be a doctor, but I discovered his talent and convinced him to

do business. They have proved to do an excellent job.”A mother of two, she believes

balancing career and family is the key to the success of a businesswoman.
Her achievements could encourage China’s promotion of a resource-efficient society and a
