By Wang Shan-yan and Dennis Xie / Staff reporter, with staff writer and CNAKaohsiung Mayor Han Kuo-yu (韓國瑜), the Chinese Nationalist Party’s (KMT) presidential candidate, yesterday said that national prosperity and harmony would be doomed if corrupt candidates are re-elected in the Jan. 11 elections. “Casting ballots for the wrong candidates will impede national development,” he said. The only chance to bring about change is to cast ballots for the right candidates in next year’s elections, he added. At a later rally in Chiayi, Han said he has found the nation’s economy to be in an extremely poor shape on his campaign trail. If elected, he would introduce bilingual education programs from the first grade, Han said.
