But who was Lady Gong Sun? Du Fu, a famous poet of the Tang Dynasty, had written a poem about her, the first two lines, when we translated into English, read as follow:
"Formerly there was a great beauty from the family of Gong Sun,
When she displayed her sword's dance everyone was deeply moved..
The game, after excellent moves on both sides, like the Sword's dance of Lady Gong Sun, comes the peace and friendly smile.
