Can you help me check the background of the guzheng song Nanniwan?

Nanniwan is a guzheng sketch adapted from the song of the same name written by 1943 by the famous Yan 'an musician Kyle. Music absorbs the tone and rhythm of folk songs and dances, which is beautiful, lyrical and dancing. Music is filled with joyful emotions from beginning to end, and it is a hymn to the heroes. This song is short in structure and simple in musical thinking. A few words outline the warm scene of soldiers and civilians singing and dancing in northern Shaanxi. After being adapted into Zheng music, we should pay attention to two special fingering methods: one is to use the middle finger "hook" to handle the hard beat and adjust the relationship between "shun" and "reverse" fingering order. For example, the alternate use of "tick-to-tick" in the second line of paragraph L avoids the repeated use of fingers and turns "anti" into "shun"; Secondly, the ingenious combination of "Goulian" and "Liantuo" not only sounds novel and unique, but also the alternating appearance of high and low voices constitutes a simple two-part rotation effect, which is unique. For example, the third line, subsections 3, 4, 5 and 6, is such a fingering arrangement. Single-fingered continuous fingering, unless it is scraping, is generally difficult to grasp the rhythm, because multi-fingered alternating playing suddenly becomes single-fingered continuous fingering under normal rhythm, which is easy to cause imbalance of center of gravity, just like our feet suddenly turn into one-legged jumping during fast running, and it is easy to fall down because of imbalance. Therefore, we should not treat such skills as "Lian" or "Lian" or "Lian" or "Wipe" lightly. We should also pay attention to methods and means while practicing, not only using fingers accurately, but also paying attention to reasonable exertion. Especially when "even tick" and "even wipe" are used alternately. Only by learning to use the reasonable transformation of inertia and symmetry and the coordination of finger force and arm force can we solve this problem well.
