When you see a subdomain like cdn.yun.sooce.cn, you're looking at a content delivery server, not a retail or business website. These endpoints are used to deliver files (images, scripts, videos) for other sites. They aren't meant to be visited directly, so the lack of an about page, contact info, or social media is expected.
The technical side looks good: the SSL certificate is valid, there are no malware or blacklist flags, and it's hosted on a well-known Chinese network. One thing we couldn't verify is who owns the main domain (sooce.cn), because the WHOIS lookup for a subdomain doesn't work that way. The Wayback Machine also has no history, which could mean the domain was pointed recently.
For what this site is β a CDN server β there are no red flags that suggest it's a scam or dangerous. If you encounter this URL as part of another site's content, it's likely safe to load. But if you have concerns about the parent domain, that's where you'd want to do a deeper check. Overall, this is not a site you need to worry about in the typical sense.
