You can use this HTML:

<iframe src="//player.bilibili.com/player.html?aid=733379562&bvid=BV1BD4y1Y7By&cid=913927393&page=1" scrolling="no" border="0" frameborder="no" framespacing="0" allowfullscreen="true">

I believe you can replace BV1BD4y1Y7By with another Bilibili video code. I'm not sure what the cid part is.

The Bilibili player doesn't provide a link to open the Bilibili page, so I would also include a link before the iframe:

[Bilibili](https://www.bilibili.com/video/BV1BD4y1Y7By/)

Thanks very much for the update! The page has been updated, it works without any issues. :cooldoge:

FYI: We have added another improvement to the spine-unity documentation page, making the SkeletonMecanim description clearer:
https://diffy.org/diff/4351ae7205946
Note: the diff might be confusing here, basically the part "instead of the Spine animation system." has been replaced with a longer section which spans multiple lines. After that, the existing sentence "As the [SkeletonAnimation]() component, it allows you to" has been replaced with "Like the [SkeletonAnimation]() component, SkeletonMecanim allows you to".

That was super quick, thanks a lot! :cooldoge:
We updated the page accordingly.

@wiige Awesome!! I have uploaded the translated file for spine-c Runtime Documentation:
spine-c 运行时文档

Only the URLs for the links to the headings in Spine Runtimes Guide or User Guide have been modified to link correctly, but otherwise the page reflects the translation file you provided as is. It looks almost perfect, but maybe you missed only the "Memory management” heading to translate:
spine-c 运行时文档: Memory management

That's all I could find, but if you find anything else you would like to correct, feel free to let me know!

Thanks for all your great work @wiige!! :cooldoge:
We have added another improvement to the spine-unity page, sorry that it happened in such a short period after the last one:
https://diffy.org/diff/fcc9b2c6604d
It mentions that users may want to call SetSlotsToSetupPose after changing skins, which hopefully will prevent some troubles for users.

@wiige Great, thank you! I have updated the Chinese page of the spine-c runtime documentation:
spine-c 运行时文档

@wiige thanks a lot for the update! :cooldoge: We have now updated the spine-unity documentation page as well.

@wiige AWESOME!! I have uploaded the both translated files:
spine-cpp 运行时文档
spine-ue4 运行时文档

Both look perfect!! I have not yet verified that all the links are working, but if there are any problems, I will fix them on my end. If there's anything you'd like to correct, feel free to let us know!

It must have been really hard to translate such a large amount of documents, but your translation will definitely be of great help to our Chinese users. We appreciate all your efforts!

Great! I have updated the Spine运行时文档 page with the latest translation:
Spine: 运行时文档

Also, I have confirmed all the links on the spine-ue4 and spine-cpp documentations. Every link should be working correctly now.

新年快乐！

@wiige FYI: We have just added a single line of example code to the Chinese spine-unity page here, as it was missing in the first skins example code block:

skeletonAnimation.AnimationState.Apply(skeletonAnimation.Skeleton); // skeletonMecanim.Update() for SkeletonMecanim

Just that you know to get the latest version before making any updates yourself.

The /markdown URLs are working for me. Maybe it was fixed since you reported it.

That like should be: http://esotericsoftware.com/spine-points
We'll fix it, thanks!

As always, thank you for the updated files!

Thanks very much for the update @wiige! We've updated the documentation page with your changes.

I cannot visit markdown text with /markdown at spine-godot Runtime Documentation while API 参考文档 works well

Perhaps the problem is just the added section anchor #spine-godot-Runtime-Documentation, as the following URL does not provide markdown for me:
https://esotericsoftware.com/spine-godot#spine-godot-Runtime-Documentation/markdown
while this URL does:
https://esotericsoftware.com/spine-godot/markdown
