GPS helps lost-and-foundPERSONAL belongings worth almost 100,000 yuan (US$12,000) have been retrieved for taxi passengers within 10 days of installing Global Position System (GPS) devices in 200 vehicles of the Guangzhou Transportation Group. The system enables the company to trace the exact position of a taxi so that things left by careless passengers can be sent back to the owners within 20 minutes. Teachers’ health alertONLY one in 10 university teachers in Guangdong is completely fit, a recent survey by the provincial education workers’ union shows. Of 8,417 teachers polled, nearly 70 per cent were in sub-standard health while over 20 per cent had succumbed to certain diseases. Cardiovascular diseases were the most common while teachers with higher degrees tended to be healthier, the survey found. Price on the riseTHE consumer price index rose slightly by 1.1 per cent last month over the previous month in Guangzhou, a survey by the city’s polling group shows. The price index for food rose by 2.7 percent as a result of the fall in supply caused by the hot weather and tropical storms. The school summer vacation also pushed up prices in the tourism and recreation markets.
