A hundred years of Qiangzhai Tianyin, the most concentrated original ecological feast here is the ocean of the big song of the village, the second day of the trip to eat breakfast in this time to listen to a little yellow song is wonderful. "The Big Song of the Dai" originated from the Spring and Autumn Period and the Warring States Period. It has a history of more than 2,500 years. It is a form of folk chorus with multiple voices, no command, no accompaniment and natural chorus in the Chinese Yi area. In 1986, at the Golden Autumn Festival in Paris, France, the Dai songs were unveiled and they were shocked. They were considered to be "clear spring-like music, passing the melody of the edge of ancient dreams." If you can choose the gender of your child, would you like? This is illegal in the metropolis, but it is a well-known secret in [Zhanli Village]. The generation is passed down by generation. The "flower-changing" is the birth secret of a family and a man. The woman gave birth to a boy in the first child, drinking the water of the female well and adding a second child called "flower change" to give birth to a girl, and vice versa. Science can't be explained today, but it is a fact that the natural population growth rate is almost zero in the past few decades. Zhanli Yuzhai built a village for more than 700 years, from generation to generation, the strict rules of the village: not allowed outside, not allowed to marry, to conservatively change the secrets of flowers and plants. And the secret of changing flowers and plants is only in the hands of a pharmacist. This ancient and legendary humanistic color adds a touch of mystery to Zhanli.
