The scene shows the arrival at the “Porte de Chine” of the military commander of Guangxi, Marshal Su Yuan Chuan (蘇元春)Yuanchun and his official entourage on 16 July 1900. The procession of sedan chairs, guarded by soldiers, had just passed through the outer gatehouse into French Indo-China (Vietnam). Marshal Su had been invited as a guest to celebrate the inaugural train of the railway connecting Hanoi with Dang Dong (同登 Tongdeng ) , close to the Nam-Quan (南關) frontier post between China and Vietnam. The large main gate, located behind the small outer gatehouse, survives today as a heritage building near today’s Friendship Pass (友誼關 s:友谊关 Youyiguan.)
