Tam Diep Mountain is a mountain range located on the border between Tam Diep city, Ninh Binh province and Bim Son town and Ha Trung district, Thanh Hoa province. <\/font>The mountain range runs to the sea in the northwest – southeast direction and has 3 peaks. <\/font>“Tam Diep” is the name of the word called in the history books and ancient geography of Vietnam, a landmark place on the ancient road of feudalism from Thang Long to the South. <\/font><\/font>Ba Doi pass<\/font><\/font><\/b>  is the Nom name of Tam Diep pass, appearing in Ho Xuan Huong’s poetry, which in ancient Vietnamese means three waves, three layers.<\/font><\/font><\/p>\n

During the feudal period, the Thien Ly road, or in some places also known as the “shift station”, Cai Quan road, the “main dynasty” road ran through Tam Diep pass. <\/font>National Highway 1A today passes through Tam Diep, there is a section that does not coincide with the ancient Thien Ly road, but crosses Tam Diep mountain in Doc Xay, the boundary between Ninh Binh and Thanh Hoa. <\/font>This stretch of road was opened by the French from Dau temple (Tam Diep city, Ninh Binh) to Song temple (Bim Son town, Thanh Hoa) in the early twentieth century to straighten Thien Ly road, avoiding having to go through the pass. The ancient Tam Diep is craggy. <\/font>Doc Xay is not an ancient Tam Diep pass because the passage through the Xay slope can only be opened by modern technology: breaking through mountains, filling deep gaps, abysses and high-level road engineering. <\/font>In 1998-1999, the Vietnamese government cut through the mountain to make a tunnel through the mountain in Doc Xay for convenient two-way travel. <\/font>Previously due to lack of conditions,<\/font><\/font><\/p>\n
