While zh-CN is present on all the other pages where applicable, it is missing for / home key even though is translated, available and usable (and present in both the language picker and the canonical meta hrefs), but not here:
You can see it's otherwise present, with about, participation, browsers pages etc. all included, just not home. Is that somehow intentional? I don't see it as a potential dupe as simplified vs. traditional are pretty far apart for, say, search indexing — and also don't see the potential confusion with .com.cn websites as they have different content? Thing is with no zh-SG or more generic zh-Hans code the zh-CN variant is basically used by all Chinese Simplified speaking communities around the world (even majorities as in Singapore), not just China mainland proper — i.e. there's consumers for that even in front of the great firewall;) and around the "western" world.
(Not that the page won't get indexed, it is, interestingly with the more generic "zh" language URL though — that may be the intention?:)
