Poet Ngo Thi Si carved one of his
texts on the grotto wall while he was a Mandarin guard in Lang Son. The
poem praises the magnificent natural beauty of the area, more
specifically the sound of the water stream falling on hundreds of rocks,
almost like a graceful murmur.
Vong Phu Mountain, meaning "waiting for a
husband," is located nearby. Here, one can explore a grotto with
marvelous stalactites and a statue of Buddha.
To Thi Mountain has the shape of a woman carrying the baby in her arms
and waiting her husband coming back from the frontier.
