It goes that a Chinese princess heading for Persia for marriage was forced to halt here by war. During her stay in the city, she got a dream, in which she was made love with the sun god and had a clever boy. When he grew up, the boy became the king of the Kingdom of Jiepantuo. From then on, they increased gradually in number generation after generation and finally formed the Tajik tribe.
