The legend of Concubine Qi originated in Dingtao County, Shandong Province. It is widely spread among the Chinese people and the Chinese around the world, and has a history of more than 2,200 years. Concubine Qi, whose real name is Qi Yi, and Ji is her title, was born in Qijiazhai (now Qiji Temple Village) in Dingtao County. She was a pioneer in textiles, music, and singing and dancing in ancient China. According to legend, during the Chu-Han War, Liu Bang, the King of Han, fought against the Overlord of Western Chu in Pengcheng. Liu Bang was defeated and fled to Qijiazhai in Dingtao. Fortunately, he was rescued by the father and daughter of the Qi family, and then married Qi Yi. In 206 BC, Liu Bang proclaimed himself emperor in Dingtao and named Qi Yi Ji, known in history as Concubine Qi. Concubine Qi was smart and clever since she was a child, very perceptive, good at raising silkworms and planting cotton, and the colorful pottery cloth she created has been a tribute to the emperor since the Han Dynasty. Qi Ji was proficient in music, singing and dancing. According to the "Miscellaneous Records of Western Capital" written by Liu Ge in the Eastern Han Dynasty, "Qi Ji was good at the dance of lifting sleeves and bending waist, and sang the songs "Out of the Frontier", "Into the Frontier", and "Looking Back". It is also said that "Qi Ji played the zither and the zither. The emperor often held his wife and leaned on the zither to sing." The legendary Qi Ji was not only beautiful and proficient in needlework and music, but also smart and brave. She followed Liu Bang in battles for many years and helped Liu Bang win the world. She was a legendary woman in the Qin and Han Dynasties. Qi Ji's legendary life has been passed down to this day in the form of oral legends by later generations.
