Currency exchange centres in Shenzhen were thrown into confusion after the revaluation of the yuan, but most visitors from Hong Kong shrugged off the impact. Exchange centres outside the Lowu border checkpoints were quieter than usual yesterday and one shopkeeper said his business had dropped by half. 'I heard the news last night, but I did not change the exchange rate until this morning. Some people are still not aware of the revaluation and have accused me of trying to cheat them,' the shopkeeper said. 'There is some confusion. People want to hold on for a while. I have fewer customers than before.' But he believed the impact was limited and expected business to return to normal in a few days. Another currency trader said business was more competitive than before. 'Many people are not sure what the rate should be and they like to shop around. We have to offer a slightly better rate to get customers,' he said. But most shoppers and visitors from Hong Kong said the revaluation had little impact. 'I'm not surprised because it is expected,' said one visitor, Kitty Chow. 'I don't think 2 per cent will make any big difference. I certainly will come to Shenzhen for shopping as usual. It has no impact for me.'
