Surrounded on All Sides, also known as The State of Han Conquers the State of Chu. The score first appeared in a collection of Pipa Scores of 1819. The Sunny Hall Collection of the Ming Dynasty contains a graphic account of the pipa master Yang Yingceng performing this piece, which belongs to the genre known as "martial suites". Its background is the struggle between Liu Bang, king of the State of Han, and Xiang Yu, king of the State of Chu, and specifically the final battle between them at Gaixia in 202. The work lauds the victor, Liu Bang. Surrounded on All Sides gives full play to all the pipa techniques ?rubbing, plucking, pushing, sweeping, etc., and the music is imbued with the stirring flavor of battle and heroism. Its narrative structure is divided into three parts: (1) Battle preparations, which is again divided into setting up camp, striking up the band, mustering the officers, forming ranks and marching off; (2) The battlefield, which is again divided into the ambush, the engagement at Cockcrow Hill and the battle of Mount Jiuli; and (3) the conclusion, which is divided into the defeat of Xiang Yu's army, suicide by the River Wu, the victory celebrations, the exploits of the generals, and returning to camp in triumph.
The Overlord Doffs His Armor also describes the battle of Gaixia, but while Surrounded on All Sides is a paean of praise to the victorious Liu Bang, The Overlord Doffs His Armor stresses the agony of the defeat suffered by Xiang Yu, king of Western Chu. Hence, the popular saying: The successful play Surrounded on All Sides, while the unsuccessful play The Overlord Doffs His Armor. With the message that heroism cannot be judged on the basis of success or failure, the latter piece of music uses mournful measures to portray the distress of Xiang Yu, the greatest hero of his time. These two complementary works are representative of the "martial suite" pipa genre.
