3. Mount To Thi
At the summit of Mount To Thi, also known as Vong Phu Mountain, there is a natural rock formation resembling a woman holding a child, gazing into the distance. This rock formation has long been associated with the legend of To Thi, a devoted woman who waited for her husband, a soldier, to return from battle in the north. After waiting in vain, she and her child were turned to stone. Hence, the mountain was named Mount To Thi. The legend of To Thi has become a symbol of the unwavering devotion and loyalty of Vietnamese women, with the image of a mother waiting for her husband at the top of the mountain becoming an iconic cultural symbol.
The mountain is also called Vong Phu (the Waiting Wife) due to the many legendary stories surrounding it.

The tale of To Thi and Vong Phu Mountain has become an enduring symbol of love and devotion, inspiring many poets and scholars throughout history.

This victory played a crucial role in ending the Ming occupation and securing Vietnam’s independence. In the 18th century, under the brilliant military leadership of Emperor Quang Trung, the pass once again witnessed victory, this time against the invading Qing forces.
