Here is Xiaoshuijing village in Fumin, Yunnan. Here everyone is a Christian. During leisure time everyone practices singing hymns. For more than a hundred years each family practices their own part of each hymn, and they have passed this tradition from one generation to the next until today. When one person sings their part alone, the singing can’t be understood, or even sounds unmelodious. However, when all the families gather on Sundays, their combined singing makes an unbelievable harmony, as if from nature itself.
