More than 100 demonstrators yesterday sang in unison outside the Taipei office of China Southern Airlines to express their opposition to controversial flight routes proposed by Beijing.

Headed by a coalition of social advocacy organizations and pro-independence groups, the protesters demanded that China cancel its plans for flight route M503, which runs close to the median line of the Taiwan Strait.
