TAIPEI/BEIJING, April 10 (Reuters) - Taiwanese are rushing to buy patches being worn by their air force pilots that depict a Formosan black bear punching Winnie the Pooh - representing China's President Xi Jinping - as a defiant symbol of the island's resistance to Chinese war games. 'SCRAMBLE!'The patch shows an angry Formosan black bear holding Taiwan's flag and punching Winnie the Pooh, with the slogan "Scramble!" - referring to what the island's pilots have had to do with increased frequency over the past three years as China sends more aircraft into Taiwan's air defence identification zone. The People's Liberation Army Eastern Theatre Command, the Chinese unit that would be at the frontline of any military action against Taiwan, released a video on Monday showing scenes from the drill, set against upbeat music
