MACAU residents are feeling optimistic and proud to be back under mainland rule, a survey revealed yesterday. The poll of 575 Cantonese speakers, conducted by the University of Hong Kong, highlighted a bullish mood in the enclave after last weekend's handover. About 80 per cent of those interviewed said they were confident about the success of 'one country, two systems', while more than 60 per cent said they were proud 'to be Chinese' again. The survey also revealed general discontent at Portuguese rule, with only 20 per cent satisfied with the previous government. Most were upset by rampant crime and corruption, which they believed had led to the recession and social instability. But nearly half hoped Lisbon would intervene if Beijing failed to keep its promise on 'one country, two systems'. More than 60 per cent believed the new Government could run Macau properly and trusted mainland authorities.
