After bidding farewell, we climb over the Ma Pi Leng Pass from which we can see and enjoy a beautiful view of sunset overlooking the Nho Que River.

Visiting these remote areas, we will bear witness to how hard the local people struggle with their environment for their survival and development. Because the living conditions are extremely hard, there is barely any arable land within the rocky mountains; the people who live there survive on a diet of corn, which is about the only crop able to grow in the rocky soil. Even through this hardship, the local people are very friendly, simple yet have developed a strong attachment to other people. They are the soul of this remote area.

Keep following the river until we meet RC 4C, near China and cross Gam River on bamboo raft into the land of Cao Bang province, where you will meet many Lo Lo, Bo Y, Dao and Giay...and visit their villages just at the roadside on the way to Bao Lac town.

Good road on RC 4 with beautiful picturesque on the Pac Lung pass before the stop in Nguyen Binh valley with green color of maize and rice fields.

Keep rolling up wild mountain pass into Cao Bang town for lunch and a short walk to see traces from the French colonialism and many stories of 1940s.
