Discrimination against HIV carriers is one of the biggest challenges facing China today in tackling the disease. But Hong Kong star and singer Leon Lai is taking one step at a time. His recent trip to the rural part of Yunnan province hopes to educate those who are still in the dark about the deadly disease.

To some, he's a heartthrob canto pop and movie star. But to these children living in the shadow of HIV/AIDS, Leon Lai conjures up hope. His three day trip to the remote Longling County in Yunnan province is part of a campaign called Local Action for Rural Children or LARC, which he helped launch in 2006.
