Why so ? My colleagues and friends in Ningbo University expected me to write a foreword for their Tour Ningbo , China's first English guidebook of its kind about sightseeing in and around Ningbo . For they believe that I am “ a recognized reference professional enough in working experience , guidebook writing and academic research to have all the say” . In addition , as the only one national-lass Tour Guide Extraordinaire in China's top tourism province of Zhejiang ,I have had special attachment both to Ningbo , the provincial biggest port city , and to domestic and international tourism I had professionally engaged in for almost 20 years before serving as fulltime professor in Zhejiang University , known as one of China's leading universities and “Oriental Cambridge” (Joseph Needham) .展开
