In 1950 the Vietminh took control of the province and the town. During February 1979, the Chinese invaded Vietnam through the border town of Don Dong (18 kilometres (11.2 mi) to the north of Long Son town). In this war, which lasted for five days, 600,000 soldiers had descended on Vietnam; Lang Son town was the major town that received the major thrust of 200,000 soldiers from China and occupied the capital city of the Northern Province. However, the Vietnamese had the last say as the Vietnamese army was successful in defeating the Chinese army, which bid a hasty retreat. This was has achieved the status of a folk lore in the province. The frontier village, which became famous during the war with China, has remnants of the war on display to the visitors. However the border has been rebuilt and brisk trade flourishes between Vietnam and China through this town.
During the Chinese invasion in 1959 the Lan Son town was also severely damaged, however it has been rebuilt since then. The old part of the town, near the Kyu Kung River has some interesting historical sites.

Historical sites

Apart from the war ravaged Dong Don Border town, which has rich war history and attracts visitors, the other historical places of interest in the province are two large limestone caves within a short distance from the Long Son town, and a 16th century citadel of the Ming Dynasty.

The two caves with Buddhist altars, well illuminated are the Tam Thanh Cave and the Nhi Thanh Cave. The Tam Thanh Cave is very large with three chambers, has water pond, and has a window opening, which provides scenic views of vast rice fields outside. The outer chamber of the cave on the right has the Tam Giao Pagoda (built in 1777) with six shrines. The second chamber of the cave on the left also shrines, the Ngoc Tuyen River flows through this cave into the mountain, an unusual feature which is described as “a dramatic sight.” The Nhi Thanh Cave, about 700 m away from the Tam Thanh Cave, was discovered in the 18th century by Ngo Thin Sy, military commander of the Lang Son garrison, whose poems have been inscribed at the entrance to the cave. A plaque erected in the cave depicts a French resident of Long Son in full European dress. The Ngoc Tuyen River flows through the cave.

The Mac Dynasty Citadel, a 16th century monument located in a desolate area on a rock outcrop, is bounded by the east-west facing walls and is approached from the Tam Tinh road from Lang Son city. Series of steps from the road lead to the ruins of the citadel.

The Lang Son city also has ancient walls built in the 18th century. A monastery existed here.

 limestone formations (also known as carbonate karst), which occupy 5% of the natural forest area of Vietnam Long Son and Cai Bang have an important place in the floral and faunal wealth of the forests. Northeast Viet Nam has 36% of the country’s 1.15 million hectares of rocky mountains out of which Lang Son and Cao Bang provinces account for a substantial part of limestone formations. According to forest statistics of Vietnam these limestone formations have 69 mammal species; five of them are endemic and 26 are rare species. Village people value these formations as they are sources of water for agriculture. They also are sources of fuel wood, medicinal plants and housing materials for the villagers. In Lang Son province they are rich source of water for irrigation of paddy crops. The limestone

. However, since the 1990s, it has decontrolled and given the trees to village families to manage.
