Concerning Chinese Cleavage Censorship

Does anyone know if there is an origin to the super specific cleavage censorship that happens in Chinese games like Azur Lane? I'm referring to the strip that covers or obscures only the cleavage. Is it an actual Chinese law/rule/edict, or is it something specific to Yostar?

Some examples:

There are a lot of other ways the game obscures cleavage (full coverings, conveniently placed hair, translucent clothing), and other times it's just shown normally, so it's not consistent across the entire game's official art.

The strip in particular seems way too specific to be a coincidence, but I can't find anything that actually discusses the reasoning for it.

Edit - I'm looking for information on it because I'd like to propose a tag since it seems like an intentional theme and style.

Just FYI, the Danbooru forum is only for matters relevant to Danbooru itself. If you want to discuss cleavage-covering outfits in a Danbooru-related context, like raising a question about how we should tag them, that's fine, but the specific reasoning behind game companies' art direction is a subject for another forum entirely.

I think he's looking for information that could potentially lead to a proposal for tagging them differently. It's pretty clear where this is going.

Just looks like a between_breasts strip of cloth to me.
The cleavage is still fully on display.

Unless this is some loophole case where the Chinese government specifically classifies the collar area as being cleavage, I can't see how that could possibly qualify as censorship. If anything, it seems intended to be the opposite, drawing the eye to the breasts by putting something that disappears between them, rather than to cover anything up.

This is where I was going, sorry for the lack of clarity, but I wanted to see if it was an actual thing and understand it before proposing it as a tag.
