The two elementary-school students graduating this year, Yang Hao-lung (楊昊龍) and Chang Wei-shih (張煒世), started out from the school at 8:30am yesterday and jogged to Jinsha Township (金沙) Office before riding a tandem bicycle to the entrance of the ancient trail into Taiwu Mountain (太武山), bordered by the Tsai (蔡) family’s ancestral house.
