There is a medium and clue in physical and visual space - the transmission pole, which runs through the entire set of works. The transmission pole is very monotonous, daily and boring, and even goes unnoticed by the public. However, the entire set of works in 'The Symphony' can continue to be shot along this thread, and one can see the author's efforts to control the atmosphere and emotional changes in the photos, striving to present a complex environment and visual rhythm under various lighting and climate conditions.

This set of photos showcases the current situation of power grid construction in the border areas of China by long-term recording of transmission poles along the Sichuan Tibet, Qinghai Tibet, Yunnan Tibet, and Xinjiang Tibet lines. The silver wires between the transmission poles stretch for thousands of miles, like musical notation, continuously sending beautiful music to various parts of the country. They have played important roles in the historical process of reform and opening up, as well as the comprehensive acceleration of building a moderately prosperous society.
