Cheng explains, "If you are going to satisfy the demands of a disparate readership, you have to offer all kinds of titles. Other important considerations include whether the time required to import books can keep pace with market trends, whether the books are what the general public wants, and whether they can meet the needs of some schools, in particular the special needs of schools teaching English and American literature."
「進書要完整，才能滿足不同讀者的需求，更重要的是，書進來的時間是否跟上市場腳步，版本夠不夠通俗，以及能否符合一些學校、特別是英美文學專業領域的需要，」鄭向榮分析。
