The H.M.G Scenic Area on the eastern suburbs of Tunxi, Huangshan city, lies in the hills and mountains along the Xin'an River's lower reaches. Among the hills and mountains and along the five-kilometre-long river are 36 grottoes. The area of Scenic spot reaches about 7 square kilometres.
On May 20th, 2001, President Jiang Zemin personally inspected H.M.G and delightedly named the Scenic area "H.M.G" with his own handwriting. He praised:" It's marvelous!

Each time when thunder and lightening happened, the strong sound wave was vibrating and echoing in the grottoes, letting out the response "wenwen" and made people tremble with fear. One of the myteries is whether the 36 grottoes connected with each other or formed alone.

If it is a shelter for troops and food or a place where the ancient people lived, it is really a secret and safe place. However, how to get rid of it dampness?
