Voice-of-Shadow Hmm, I believe it's a misunderstanding that users can't post using the Tutorials
tag or that Chinese translations aren't available. However, I am aware that the translation button sometimes doesn't appear for some reason! When we renewed the forum system, we encountered the same issue several times within the team, but unfortunately, we still haven't found a solution. In most cases, refreshing the page or reopening the thread should resolve it. At least on my end, the translation button is working:

As stated in the Tutorials
tag guidelines post, this tag is specifically intended for users to post useful information. While it's true that the Editor
tag is also acceptable, it tends to be used much more frequently. Since threads tend to get buried quickly in the Editor section, I thought using the Tutorials
tag would be better for keeping valuable information visible at the top.
Although I did consider whether the Showcase
tag might be more appropriate as a ‘presentation’ of research results, I felt the article and past videos you linked to were sufficiently educational, so I thought Tutorials
was the right choice.
