Wang Huiran wrote in "Experience of Yi Dance Music Creation": "At that time (1956), we waded through mountains and rivers with Yi and Miao caravan every day, often standing on clouds and holding the blue sky overhead, enjoying the majestic and picturesque scenery of 100,000 mountains. We were still on the road at two or four in the morning. The bright moon is in the sky and the night is charming, competing with the hazy scenery of the earth. These are the artistic conception described in the preface of Yi dance music. " "On the way to March, the villagers who drove the caravan often sang unique and colorful Yi folk songs and folk songs for us. We also paid attention to their performances and learned a lot of folk songs and dances. One of the most touching is Yi Wu's "Cigarette Box Dance" (also known as "Brand Hole Embroidery"). Its beautiful and moving dance, soft and beautiful melody and light and elastic rhythm left an unforgettable impression on us. Together with other colorful Yi music, it provided a solid life foundation for yi dance's music creation and accumulated rich music materials.
