A simple flower made headlines in the British press last week. How could that be?
British Prime Minister David Cameron and his ministers were attending a reception hosted by Chinese Premier Wen Jiabao in the Great Hall of the People in Beijing. They insisted on wearing poppies(罂粟花) in their buttonholes.
