why the dictionary can not translation chinese

most likely because the person who wrote it speaks only english.
if you need an chinese to another language translation dictionary, you can find many of them on the internet. if you're living in china, i don't think the communist party bans these sites, so you can just google them some use simplified chinese, some use traditional, some use pinying. some even let you enter character strokes.

Which chinese dialect and to which language?

Someone has to write the dictionary first, is usually the problem

For Cantonese there are some resources here:

For Manadarion, I think there may be some resources here; I don't know, I don't speak mandarin.

Stardict is a cross platform dictionary, but its a bit fiddly to set up. they have a page here, but the english version is hard to navigate:
