They checked the most important moments in each person's life, looked for details about such moments, especially the emotional ones and showed them in the production.

"For example, when we tell the story of New Fourth Army soldier Yin Feng, we interviewed her three children. One of them said when they were young, their mother was so busy at work that sometimes she ignored the children. One day they waited for her to pick them up after school, but she didn't come, so the three children hugged together and cried. Finally they were sent back home by a nurse of the school," says Guo.

"We focused on people's emotions in the program, and I believe they are touching at any time. We want to see in the face of the historical changes, how they made choices, how they insisted on their choices and how they played their role," he adds.

Guo says he was influenced tremendously by the women in making the program, and hopes more people will learn from them. "Shooting the program often makes me feel I travel to the times of the heroines. I have female family members, but the program gives me a different angle to view and understand women," says Guo.

"I believe the great women are role models of current young people, and their story will strike a chord with the audience," he adds.
