啊啊啊……
我英语不行，但好喜欢这个软件呀
可是，汉化不行，用着太难受了，就一直没购买
求求了，给我个花钱的机会
汉化很难吗？做一下吧，呜呜呜……
错字，汉化很难吗？求求你们好好弄一下行不行……
我好不容易找到这么好用的软件，要哭了，汉化，汉化，汉化
激动地又打错了字，汉化很难吗？做一下吧
这些天又尝试了别的软件，但还是喜欢这个
There is a chinese preview avaliable in Scrivener 3.0 for windows. It’s on File > Options > General > Language. There you can choose the chinese preview (it’s at the bottom).
I don’t think it has everything translated, because other previews don’t either, but it definitely will be more comfortable.
Hope it helps
求求了，咱们把中文汉化做一下吧，实在用不来半英半中的页面
我试用了这个软件，觉得很棒，想购买，可是汉化太差了，拦住了我
好希望能完善一下呀
拜托，拜托
好奇怪啊，为什么我打字发出去会出现错误，唉
非常感谢你的回答
我知道可以设置中文简体
但就是这个软件翻译不完全才教人难受
我实在不懂，这么好用的一款软件为什么不好好做一下语言翻译呢？
痛苦，希望有生之年能看到这款软件变得更加完美
I have a similar issue with the spanish translation (I’m not a native english speaker). It doesn’t have everything translated and it’s uncomfortable sometimes. I’m thinking of making a suggestion to let Scrivener users help translate the software. I’d gladly help fully translate this software. Or, at least, it could have an option for us to unofficially translate the software ourselves, I don’t know…
Meanwhile, I think there are apps and softwares that automatically translate everything there is on the screen.
These are often pretty bad for stuff like software. The jargon is what tends to get in the way, and you end up with awkward things like referring to the binder as a “flastener” or screenplay characters as “letters”. 
If you’d like to volunteer to maintain a particular language though, feel free to get in touch.
朋友,這套軟件是有中文,可以在設定內選擇,不過有關的中文就要自己腦補一下了.
請教一下,閣下是寫網文的嗎?
