I could not get it if it is a verb or an adjective.If it is a verb, to talk a lot in a way that expresses emotion or enthusiasm, shouldn't the word euphoric have written "euphorically" also ?
Perhaps nowhere else in China more than in Beijing is the generation gap more visible. Appalled by the current drive to “modernise”, many older people still wax euphoric about Chairman Mao and the years of sacrifice for the socialist revolution. But most youngsters disdain socialist sacrifice and are more interested -like youngsters everywhere - in money, motorbikes, fashion, video games and rock music .
