A supporter of Taiwan's opposition Democratic Progressive Party, DPP, covering up his mouth with a Chinese sign reading "good health," holds a portrait of Taiwan's President Ma-ying jeou resembling Adolf Hitler during a protest against lifting certain restrictions on US beef imports Thursday, Oct. 29, 2009. Ma sought to ease a political storm over the government's decision to lift a ban on U.S. beef imports Thursday, saying meat importers are taking the steps of preventing mad cow disease by imposing a voluntary ban.
