I didn’t know we were to squeeze through a crack in the rock while we were hiking up the hills of WuYiShan, China.
The rocks seem to be slanted in one direction and between the rocks there is a narrow gap.
More to this, no light can reach the gap and we have to make our way up the gap in darkness.
The gap is called ” A Thread of the Sky”.
From this, you can imagine how narrow the gap is.
The second photo was taken from a distant after emerging from the gap.
