In the twenty-sixth year of the Republic of China, Xu Zhusheng, a piano master from Jiangnan, received the last letter from Peiping. The letter paper was stained with blood, and there was only one line: "It's cold in the north, so take care and put on clothes." The handwriting was scrawled, but it was like a piano string that plucked his silent heart. The Japanese army marched south, but he went upstream against the current, carrying a Tang qin with broken strings, and traveled thousands of miles through the flames of war, just to find his confidant who once discussed the qin in the theater and listened to the rain under the moon - underground worker Ye Huaiqiu.
Purpose: To protect the fire of civilization and the true feelings of the world in a broken era, and to show the profound connection between the character of scholars and the feelings of family and country.
