Lou Jing sings Shanghai opera and speaks fluent Mandarin, but when she competed to be China's next reality TV pop star, it was not her voice that was criticised -- it was her black skin.
The daughter of a Chinese mother and an absent African-American father, 20-year-old Lou caused a media storm when she was named one of Shanghai's five finalists for "Let's Go! Oriental Angel," an "American Idol"-style show.
But her fame has been for all of the wrong reasons, after her appearance sparked a vigorous and often vicious nationwide debate on whether she was even fit to be on Chinese television because of the colour of her skin.
Ahead of US President Barack Obama's first visit to China, Lou's experience has put a spotlight on perceptions of race in the country and the challenges the Asian giant faces as its economic boom fosters a more ethnically diverse society.
"I am Chinese," Lou told AFP in an interview. "But when I read the comments, I started to question myself. I never questioned myself before. This time I started to think about how I am different from others."
Even though Obama is wildly popular among the Chinese people and the country is rapidly expanding its ties with Africa, commentators said Lou's story exposes deep racism in China, where the ethnic Han are in a vast majority.
"In the same year Americans welcomed Obama into the White House, we can?t even accept this girl with a different skin colour?" wrote Hung Huang, a talk show host and magazine publisher often described as "China's Oprah Winfrey."
