What is the name of Qian Xuesen's farewell song?

: I yuè

Sad music dedicated to funerals or memorial services. Different countries, different nationalities and different historical periods have different contents of funeral music and different ways of playing and singing. The funeral music currently used in China is selected from the folk music in Ansai area of northern Shaanxi. In the early 1940s, when Yan 'an musician An Bo went deep into Ansai area to collect folk songs, he collected a classic funeral music. 1942, Liu Zhidan's coffin was moved to Baoan County (now Zhidan County). At the meeting of Liu Zhidan, the people's public sacrifice in northern Shaanxi, Amber wrote lyrics for this song for the first time, played this song and named it Comrade Zhidan. At that time, the band of Lu Xun Art College in Yan 'an undertook the task of playing music. Since then, this kind of elegy has gradually spread in Shanxi-Chahar-Hebei and other liberated areas. After 1949, Luo Lang, the first conductor of the China People's Liberation Army Military Orchestra, arranged the harmony for this song as a ceremonial song of the military orchestra.

1936, Comrade Liu Zhidan led an expedition to the East under the instructions of the CPC Central Committee, and unfortunately died in Sanjiao Town, Zhongyang County, Shanxi Province. 1942, the CPC Central Committee decided to move Liu Zhidan's coffin to his hometown-Baoan County (now Zhidan County). In order to make the ceremony more grand, "Lu Yi" band undertook the task of shifting spirits to play music, and five musicians, including Kyle and Amber, formed a funeral music creation group. They adapted it into formal funeral music according to the folk funeral songs that were widely circulated in Shanxi and Shaanxi at that time. This kind of funeral music with China national style has been used to this day.
