Many Chinese celebrities are actively involved in charitable causes, such as Jet Li's One Foundation and Faye Wong's Smile Angel Foundation.

Celebrities are believed to have advantages in making public appeals and raising money, but their words and deeds are coming under the scrutiny of the media as well as millions on the Internet.

Experts agreed that China's charitable causes need more support as the system improves.

"It's good to see netizens join the supervision of charity efforts, but the core issue is to improve its system," Chen said.
