The Springbok Sevens began their Hong Kong campaign with a 31-7 win against France.
Seabelo Senatla rounded a French defender to score the opening try of the match, before Virimi Vakatawa broke two tackles to level the scores.
But it was one-way traffic from then on, as Justin Geduld scored before half-time and Senatla, Cecil Afrika and Werner Kok all went over in the second half.
The Blitzboks will play their other pool matches, against Spain and Australia, on Saturday.
