Beside the limestone blocks creating countless unique shapes, there is another strange thing formed in the Ngườm Ngao cave, which is two stone sprouts recently discovered in the second line resembling the reproductive form of a man.

It is said that the people here once prayed for favorable rain, gentle winds, a warm and prosperous life, and many descendants, so the mountain god here created two stone sprouts that symbolize fertility for those who come to pray for many children.

These two stone sprouts are completely natural, without human intervention, and unintentionally over millions of years, the two stone sprouts have taken on the shape resembling that of a man.
