This is the Xiandai Hanyu Guifan Cidian (Standard Dictionary of Modern Chinese). I bought it in China but you can also get it on websites selling Chinese language products (e.g. http://www.aolifo.de). It’s a Chinese-Chinese dictionary, all main entries are with pinyin and explanations are Chinese only. I recommend it for upper-intermediate and advanced learners.
Let’s say we want to look up the word “lǔmǎng”.
We find the entry 卤莽 but the dictionary tells us that the word is written 鲁莽 nowadays.
And here we find the explanation. The character in the square shows the part of speech (here: adjective). The hand symbol reminds us one more time that we shouldn’t write the word with the characters 卤莽.
Pleco, a very useful Chinese dictionary app for mobile phones, offers Chinese-English and English-Chinese. You can get it for free but if you get the professional bundle (it’s 64,99 €; you can also only choose individual add-ons you need), you get access to a lot more dictionaries and even Chinese-Chinese dictionaries like the one above. So let’s check Pleco for the same word.
The main entry already shows us that they are two possibilities of writing this word. We scroll downwards to the Chinese-Chinese dictionary.
GF is the abbreviation Pleco uses for the name of the dictionary. And here we see the exact same reference. We click on the characters in blue.
And again we get the exact same entry with the explanation. The character in the square is now just grey and the hand symbol has been changed to 注意 (warning).
Now imagine we don’t understand the explanation. We can just tap on the characters we don’t know.
A small window pops up showing us the pinyin and the English translation. So I highly recommend Pleco for every serious Chinese learner.
If there is any similar dictionary app for Japanese out there, please leave me a message.
