Standing at the Dongxing Port National Gate Scenic Area, the five-star red flag flutters in the blue sky, the "China Dongxing" boundary marker stands majestically, and the China-Vietnam Friendship Bridge, like a giant steel dragon, spans the Beilun River, connecting the territories of the two countries. This is the southwesternmost border gate of the motherland's mainland coastline, separated from Mong Cai, Vietnam by only a hundred meters. Every inch of this land bears the imprint of "the majesty of a great power." Standing before the boundary marker and looking back, behind me lies a vast landscape, and before me, exotic scenery unfolds. The solemnity of the border and the strength of the motherland strike the heart at this moment!
