On a typical hot August day in Xianyou County, Fujian Province, Zeng Demei, a retired worker in his seventies, hurries down a busy street．In his hand is a black leather bag．Zeng opens his bag, taking out two forms．  71  

Each of the forms contains detailed information of a student．On his arrival two hours later a woman greets him and leads him to her office where another man is waiting．They are the two village officials．They inspect the forms handed to them by Zeng and immediately recognize the girls． 72   ? "It’s a pity but it doesn't matter．" says Zeng, who wastes no time in deciding to look for the remaining child, Su Qiuju．
