When South African Motswedi Modiba made her first appearance on Sing China, one of the world’s biggest TV shows, the video went viral. It wasn’t just because she sang the song beautifully or because she belted out the words in perfect Mandarin. People were also excited because she became the first black African to appear on the show. The show has more than 150 million viewers and since her audition, she’s picked up thousands of new followers across Asia.
