At dawn on February 17, 1979, China launched a surprise advance, simultaneously attacking six border provinces from Nam Cun (Lai Chau) to Po Hen (Quang Ninh).
In Mong Cai, heavy artillery and various types of firepower heavily bombarded Border Guard Posts 209, 210, 211, and 212, as well as forestry worker teams and residential areas along the border line.

The enemy split into five directions to relentlessly attack Po Hen post; the border guard soldiers fought with utmost bravery to repel the assaults. However, due to the disproportionate balance of forces between about 60 soldiers and more than 3,000 enemy troops, 45 soldiers sacrificed their lives alongside a group of Hai Son forestry workers and female commercial worker Hoang Thi Hong Chiem.

On January 10, 2001, on the grounds of the former barracks, a memorial was erected. In 2014, the 209 Po Hen Border Guard Post relic was recognized as a provincial-level historical relic. By 2022, the Po Hen Relic Site was ranked at the national level.

The Po Hen Historical Relic Site comprises four locations: the Po Hen Martyrs' Memorial, Que Hill outpost, Po Hen border gate checkpoint outpost, and West Hill observation post. Among them, the monument cluster designed around the concept of "Comrades' Embrace" stands out prominently.

The five-pointed star in the center symbolizes the steadfast spirit of the border land and its people. Beside it are two stele houses, where two stone steles are placed bearing the names of border guard officers and soldiers, and forestry workers who fell during the period from 1979 to 1991.

Every year on February 17, the Po Hen Border Guard Post holds a joint memorial service for the martyrs. And in 2010, the Po Hen relic site underwent renovation on the occasion of the 110th anniversary of President Ho Chi Minh's birthday.

The Po Hen Relic Site has now become a "red address" in educating on the tradition of fighting to protect border sovereignty, encouraging and motivating younger generations to continue writing the heroic pages of history of the border guard force in particular and the Vietnamese nation as a whole.
