Which is better, the electronic dictionary Haoyitong CD 780 or the Kuaiyidian all round A850

I bought the A850 and I think it's good because the screen resolution is higher than the average black and white machine. There are many dictionaries, and the words you want to look up can basically be searched. I used to use a good and easy-to-use dictionary, and I felt that I couldn't find many new words.

For college students, a good electronic dictionary should at least include the entire "Oxford Advanced English-Chinese Dictionary" or "Longman Dictionary of English-Chinese Dictionary" (generally the electronic dictionaries that include these two dictionaries are authoritative editions authorized by Oxford University Press or Longman Publishing).

These two dictionaries, both in terms of entry arrangement and explanation of example sentences and grammar, are "classic + authoritative". The entire electronic version of the dictionary is included, which makes it easy to find relevant entries and grammar, and there are also derived words for associative memory.

Oxford Advanced is a copyright dictionary In China, only Haoyitong and Haojixing have this copyright. Everything else is pirated or incomplete Understand it I don't think you can use the n homework of Hao Xingxing to learn at the same time Then in terms of professionalism and quality I recommend you to buy the electronic dictionary of Haoyitong There is nothing to say about the vocabulary and professionalism The quality is also very good According to your requirements I recommend you CD500 which is better at a price of about 400-500, depending on which point of view you look at.

Spelling dictionary (I mean English dictionary,Chinese dictionary or encyclopedia and the like),Haoyitong CD580 will undoubtedly lose,Its main one is a "Oxford Advanced English-Chinese Dictionary (Seventh Edition)", celebrities s668 has six Oxford dictionaries: "Oxford Modern English-Chinese Dictionary", "Oxford Advanced English-Chinese Dictionary", "Oxford English Collocation Dictionary", "Oxford English Synonym Dictionary", "Oxford Phrase Verb Dictionary", "Oxford English Idiom Dictionary". Let me say more, although the "Oxford Modern English-Chinese Dictionary" is much more expensive than the "Oxford Advanced English-Chinese Dictionary", but it may not be of much use to you at the moment (I assume that you are a beginner and intermediate level), so the celebrity s668 is a more useful learning dictionary for you is the "Oxford Advanced English-Chinese Dictionary", from the name, "advanced" is one level lower than "advanced", if you are a middle school student, advanced enough, if you are a college student, you need a high draft, you may be confused when you see this, Isn't this better for the CD580?

I haven't finished talking yet, in addition to these dictionaries that celebrities come with, they can also download copyright dictionaries for celebrity electronic dictionaries on the Internet: Oxford Advanced, Longman Contemporary, Collins, Merriam-Webster, American Tradition, ......You will definitely wonder why the key socks are not available on the Internet**Copyright Dictionary,I can't explain this,I can only say that after my verification is indeed a copyright dictionary,I use it very comfortably (I myself use celebrity s928)。

In addition, the ** of the celebrity S668 is lower than that of the Haoyitong CD580 (reference ****).

However, celebritiesS668One thing I am not satisfied with is that the lower left corner of the keyboard panel is too sharp,It feels very awkward when you hold it in your hand,It is recommended that the landlord personally go to the mall to use it。
