In 1985, the eighth day of the twelfth lunar month, Qingniu Village, Dongguang County.
It has been three days since heavy snow closed the mountain.
The entire Qingniu Village seemed to be trapped in an upside-down white porcelain bowl, and even the barking of dogs was frozen to pieces. In a low adobe house at the east end of the village, five-year-old Lin Chen huddled in a tattered quilt, covered with the only cotton jacket in the family - it was a dowry from his mother Chen Guizhi.
