The Sun-and-Moon Twin Sabers are Hu Sanniang’s paired weapons in Water Margin. The two blades distinguish the mounted warrior through the speed and coordination of her fighting, rather than through an extraordinary size or magical effect.
Chapter 48 names the pair when she rides to support the Zhu Family Manor. She overcomes Wang Ying, hangs up her right-hand saber, and pulls him from his saddle. Later, her exchange with another double-saber fighter turns the paired blades into a dazzling display of movement.
The sun-and-moon name belongs to the text. It does not establish a solar blade, a lunar blade, or a fixed system of elemental powers. The pair expresses Hu Sanniang’s assured skill and makes her instantly legible among the mounted heroes.
