Chinese top tennis player Li Na promises to donate all the prize money to Yushu orphans in the press conference before the China Open kicking off on Oct 2, 2010.

Yushu in northwest China's Qinghai province was jolted by a massive earthquake in April.

Just a few months ago, Li donated 400,000 yuan to help Yushu orphans in May after she played the Madrid Open.

Chinese Grand Slam semifinalist Li Na, who quit the Pan Pacific Open with a stomach ache on Monday, is eager to perform well in Beijing and earn the requisite number of points to qualify for the Doha tournament, as China Daily reported.

According to the shedule, Li Na will play her first match against Alla Kudryavtseva (Russia) with China Open this year at the Lotus Court in Beijing this afternoon, Oct 3, 2010.
