In the green pine and fir forests, layers of terraced fields are half-way up the hill, reflecting the Yao villages which are scattered and built according to the mountains, enjoying the Yao people's homemade bitter mulberry wine, enjoying the Yao people's bamboo bar dance, top bar and harvest dance performed for us by Yao boys and Yao girls, wearing Yao people's own embroidered colorful pattern costumes, drinking sweet Yao mountain tea and eating delicious bamboo shell rice. It feels like something different on earth.
