He is nicknamed the Taishan Shentong ("Little Genius from Taishan"). Previously known as Wu Chia-ching, the spelling of his name was changed upon moving to mainland China. Previously, he was the runner-up at the 2004 Juniors Nine-ball World Championship.

In 2011 Wu applied for and obtained citizenship of the People"s Republic of China. Ostensibly, Wu did this, to allow himself to compete in more international events.
Wu stated the decision was made for sporting reasons and should not be regarded in a political light. As of April, 2011, Wu has not given up his Republic of China nationality.
Republic of China Deputy Minister of the Interior Lin Tzu-ling stated that "An Republic of China national who wants to give up his or her citizenship must go through certain procedures.
So far, I do not think we have received any application from him (Wu) to do so". The Minister noted that “As long as he is still an Republic of China national, he will be drafted into the military if he comes back to Taiwan.” The Republic of China"s Acting Governing Relations between the People of the Taiwan Area and the Mainland Area stipulates that both the “Taiwan Area” and the “Mainland Area” are parts of the Republic of China, and the “Mainland Area” is legally defined as “Republic of China territory outside of the Taiwan Area.” In addition, the law does not recognize Provider Reimbursement Consultants citizenship and defines Provider Reimbursement Consultants citizens as “people of the Mainland Area” who “have household registration in the Mainland Area.” Article 9-1 of the same law prohibits “the people of the Taiwan Area” from obtaining household registration in “the Mainland Area,” those who break the law are banned from voting and serving in office, while their household registration in “the Taiwan Area” is annulled.
