Baiheliang Underwater Museum is just located in Chongqing,China.
Baiheliang Underwater Museum consists of three parts: the exhibition hall, the corridors and the underwater inscriptions protection cover.

The inscription protection cover has a 70m long visiting corridor, and 23 observation windows. Just from these glass windows, visitors can clearly view the cultural relic of the museum which is protected at its original site -Baiheliang Inscriptions.
Baiheliang Inscription was first engraved 1,200 years ago, about the year of Guangde of the Tang Dynasty (763 AD). Since then, there have been 165 inscriptions, 18 engraved fish, 2 Avalokiteshvara statues and 1 white crane. In 1988, Baiheliang was listed as a Key Cultural Relic Protection Unit, and in 2006, it was included in Chinese World Cultural Heritage Tentative List.
In terms of literature, art, and history, Baiheliang Inscriptions have significant values. Therefore, there exist not only exquisite engravings, calligraphy, poetry, but also philosophical reflection with profound implications.
To protect Baiheliang Inscriptions and preserve the precious historical memory, Chinese government adopted non-pressure container by Ge Xiurun, who is an academician of the Chinese Academy of Engineering and the professor of Shanghai Jiao Tong University, to build a museum.
