Tan Ruyin sealed the victory for China through a lob shot from 40 meters away in the 87th minute.
Gu is the only one who ever played in the Beijing Olympics on the current Chinese squad.
"I was too young eight years ago, but now as a veteran I hope to bring our team victories again and again," Gu told Xinhua.
Bini was very excited about Tan's incredible lob shot.
"If this goal was scored by Lionel Messi it would be played for at least a week all over the world. But if it's a Chinese girl it will only be played in China for a shorter time. This is the difference between men's and women's football," said the 61-year-old Frenchman.
