What does RTH stand for? I am guessing "something something To Kanji/Hanzi".

The deck you linked is not mentioning HSK in the description though. It was maybe 1 year ago or so, that I searched for HSK1-3 level decks and only got wrong direction ones.

I am searching again now:

(1) "HSK1 English" -- nothing

(2) "HSK1" -- lots of results, but also tons of results that are not relevant for me, because they are not for English. -- Results like https://ankiweb.net/shared/info/1474834583 -- but that is 1-4 which is too much for me. I either need the 1, 2, 3 levels separate, or 1-3 in one deck. Also finding https://ankiweb.net/shared/info/166845167, which is the wrong way around. Starts right away by asking me "的" instead of something like "(some description here)". When I go to deck options in Anki desktop app, I see "Display Order", but there I cannot select any "English -> Chinese". Tons of options, but none that inverts what the cards show.

One sibling comment informs me, that I have to edit a template somewhere. But I don't know where, and in the deck options I don't quickly see any template editing function.

And this has been my experience with pretty much every HSK deck I found there. It would seem silly, that everyone uploads decks in the "wrong" order. Which leads me to think, that many people cheat themselves, by only doing the recognition part of learning the characters. Why else would so many people upload decks, only so that whoever who downloads the deck has to invert them first, before using them. I also think that many learners are probably not aware of the issue with seeing the character first and then translating to English, in comparison with doing it the other way around.

So now lets do your "RTH" search:

"HSK1 RTH" -- " Error: Please log in to perform more searches."

I am sorry, I cannot even do a keyword search a couple of times??? I need to log in, requiring an account (!) to even find a suitable deck?! OK, at this point I give up again.
