约翰欠汉,越汉越汉--Oxford < English Chinese dic. < Chinese-English dic.

A New Oxford Advanced Learner\'s Dictionary is compiled by three foreigners, with no Chinese advisors assisted, I assume. Their choice of Chinese definition is inferior than that of A New English-Chinese Dictionary, which is by Chinese, foreign advisor is also not seen.
Again, Chinese-English dictionary contained more Chinese items, but needs to add more ways for searching.
新牛津高階英漢雙解詞典編制by 3名外國人，沒有中國顧問的協助，我assume.他們選擇漢語的定義較新英漢詞典是劣勢.新英漢詞典是由中國specialists，也沒有外國顧問。
同樣，漢英dic.含更多的漢語項目，但需要增加更多的方式搜尋。
