Three to the good...Fourth-grade pupils from Dexing Street Primary School in Jinan, capital of East China's Shandong Province, yesterday try their hands at making a wood toy at the provincial Science and Technology Hall. Chinese schools are trying to revamp a 50-year-old system to promote good all round behaviour in primary and middle school students. The "three-good" student honour system, extolled the virtues of good morals, hard study and sporting excellence.
