Participating celebrities will visit the most poverty-stricken areas in rural China to promote local commodities and tourist attractions.

Their charity activities will be featured in the documentary Starlight directed by Zhao Wei, an actress-turned-filmmaker who shot to prominence from the hit TV series My Fair Princess, and nine young directors. The feature's theme song is composed by Chinese-American singer-songwriter Leehom Wang.

Seven stars already toured some poverty-stricken areas before the ceremony.

Along with Chan, who toured six towns in Shanxi province, actress Zhou Xun, who earned popularity for the Qing Dynasty-set drama Ruyi's Royal Life in the Palace, trekked to Zhaojue town in southwestern Sichuan province.
