The trek is actually the result of an agreement between Lu Yue and her father, Lu Qingfeng. Before this year's college entrance exam, Lu Qingfeng proposed to his daughter that if she got admitted to a university, wherever it was, they would trek to the university. Lu Yue agreed and later her younger sister decided to join them.

A workout enthusiast himself, Lu Qingfeng pays much attention to his daughters' physical exercise. He has been running for nearly 10 years.

Regular exercise gives his daughters stronger bodies than their peers, as well as their sunny and optimistic dispositions.
