How many passages is the famous musical work "House of Flying Daggers"?

Throughout the whole song, House of Flying Daggers shows the battle between Liu Bang and Xiang Yu in 202 BC. It can be roughly divided into three parts and thirteen paragraphs:

The first part is the preparation of the Han army before the war. Including five sections: fighting, blowing, pointing, platoon and walking. At the beginning of the music, the pipa played a sonorous chord symbolizing the sound of drums in the high-pitched area, presenting us with an ancient battlefield scene with empty flags in the military camp. The relaxation of music rhythm, the change of mode, the change of range, and the extensive simulation of various fingering changes such as drums, bugles, hooves, footsteps, guns, etc., have produced dramatic effects: beating drums, beating horns, shooting, blowing horns, opening doors ... vividly depicting the scene of the Han army dispatching troops before the war.

The second part, the thrilling war scenes of Chu and Han armies. Including "Ambush", "The Little Battle of Jiming Mountain" and "The Battle of Jiulishan" are the core parts of the whole song. Among them, "Ambush" has a tense and horrible atmosphere. At this time, the speed is getting faster and faster, the intensity is getting stronger and stronger, and the melody is increasing and decreasing. Like the night, the ambush is heavy, and the war is imminent. Sentinel War vividly shows the small-scale battle scene of hand-to-hand combat between the two armies. Then, the intensity was constantly strengthened, the melody was ups and downs, and the climax of the whole song-"War" began. Music uses a variety of playing techniques, such as "sand", "double string" and "push and pull", which vividly renders the whole battlefield atmosphere: thousands of troops, fighters, drums, swords and shadows.

The third part is the end of the Chu-Han War. It includes five paragraphs: Wang Xiang's failure, Wujiang's suicide, all the troops won the battle, and all the generals returned to the camp for meritorious service and victory. The passage "The Defeat of Wang Xiang" is an interlude in structure, and there is hardly any melody at all. Music homophonic repetition, gradually accelerating from slow to fast, is dominated by scattered rhythms, such as horseshoes, and then seems to be catching up with the rhythm, showing the scene of Xiang Yu and several of his men breaking through. The whole atmosphere of Wujiang commit suicide is low, and the tune is tragic and sad, which shapes the complex mood of the failed hero Xiang Yu. At the end of this paragraph, after "pressing" on the low chord, the sudden "falling" came to an abrupt end. The three paragraphs after "All Armies Play Kai" describing various scenes after the victory of the Han army have been deleted by modern performers, and "Wujiang commit suicide" ends as a whole song.
