If you’re looking for a clean, unmodified, official LinxOS 6.0.99 SG security-enhanced ISO, you’ve come to the right place.

LinxOS is one of China’s longest-standing security OS vendors, and the SG (Security Guard) edition is the highest security tier in the product line. On top of the standard edition it layers full mandatory access control, separation of administrative duties, and trusted-computing measurement — built for power dispatch, defense, and classified government environments. Trustworthy public mirrors of such industry systems barely exist, so a genuine source plus a verifiable hash is the baseline.

If you’re looking for a clean, unmodified, official NFSCNS 4.0 G340 ISO, you’ve come to the right place.

NFSChina (National Fundamental Software of China) is a veteran domestic infrastructure software vendor. Its trusted server operating system (NFSCNS) has long served mission-critical government/enterprise workloads and IT-innovation infrastructure, with deep expertise in security hardening, stability, and the domestic hardware/software ecosystem. 4.0 G340 is an iterative release in this product line. Original images of server systems built for critical business are hard to find through public channels, so a genuine source plus a verifiable hash is the baseline for production deployment.

If you’re looking for a clean, unmodified, official NFSDesktop 5.0 G240 ISO, you’ve come to the right place.

NFSChina (National Fundamental Software of China) is a veteran domestic infrastructure software vendor. Its desktop operating system has long served government and enterprise office scenarios, with solid adaptation to domestic CPUs and office software ecosystems. NFSDesktop 5.0 G240 is an iterative release in the 5.0 series. Original images of these enterprise-focused distributions are hard to find through public channels, so a genuine source plus a verifiable hash is the baseline for a worry-free installation.

If you’re looking for a clean, unmodified, official NingOS V3.0 AArch64 ISO, you’ve come to the right place.

ARM64 images of domestic Linux distributions are hard to come by — and for a niche distro like NingOS, trustworthy sources are even scarcer. Most links circulating online can’t be verified. This post provides the NingOS-V3.0-1.0.2509-aarch64-dvd.iso official image, with a PowerShell-verified SHA-256 hash so you can confirm every byte matches the original release.

If you’re looking for a clean, unmodified, official openEuler 22.03 LTS SP4 ISO, you’ve come to the right place.

Since CentOS reached end-of-life, openEuler — the open-source server OS community initiated by Huawei and hosted by the OpenAtom Foundation — has become one of the most active enterprise Linux ecosystems in China. But the official mirrors aren’t always fast for every network, and third-party repackaged images are a risky foundation for production servers. A genuine source plus a verifiable hash is the baseline.

If you’re looking for a clean, unmodified, official openEuler 24.03 LTS SP3 ISO, you’ve come to the right place.

Since CentOS reached end-of-life, openEuler has become one of the primary choices in China’s server ecosystem. 24.03 LTS is one of the community’s newer long-term support branches, moving to the 6.6 kernel with significantly better support for next-generation CPUs, AI acceleration hardware, and cloud-native workloads. SP3 is a mature service pack accumulating extensive stability fixes and security patches on that branch. Official mirrors aren’t always fast for every network, and third-party repackaged images are a risky foundation for production servers. A genuine source plus a verifiable hash is the baseline.

If you’re looking for a clean, unmodified, official openKylin Desktop V3.0 AgentOS ISO, you’ve come to the right place.

openKylin is an open-source desktop OS community incubated by the OpenAtom Foundation. The V3.0 AgentOS release deeply integrates AI agent capabilities into the system — natural-language computer control, a system-level AI assistant, and on-device LLM support — marking the shift of domestic desktop systems toward being “AI-native.” After a major release, repackaged mirrors spread fast, so a genuine source plus a verifiable hash is the only way to be sure you’re installing the official build.

If you’re looking for a clean, unmodified, official Red Flag Asianux openEuler v8.1 DT Desktop ISO, you’ve come to the right place.

Red Flag Linux is one of China’s longest-running Linux vendors. Alongside its well-known server products, the Asianux line also includes a DT (Desktop) edition built on the openEuler ecosystem — bringing the Euler technical foundation to PCs and office workstations. Commercial desktop distribution images like this are hard to find through public channels, so a genuine source plus a verifiable hash is the baseline for a worry-free installation.

If you’re looking for a clean, unmodified, official Red Flag Asianux Server openEuler v8.1 ISO, you’ve come to the right place.

Red Flag Linux is one of China’s longest-running Linux vendors, and its server product line Asianux has been deployed across telecom, finance, energy, and government sectors for years. openEuler v8.1 is Red Flag’s server OS release built on the openEuler open-source ecosystem — combining the community’s technical foundation with Red Flag’s enterprise support experience. Commercial distribution images like this are hard to find online, and third-party repackaged images are a risky foundation for production servers. A genuine source plus a verifiable hash is the baseline.

If you’re looking for a clean, unmodified, official RedFlag Desktop 11.0 Alpha LiveCD ISO, you’ve come to the right place.

Red Flag Linux is a pioneer of Chinese operating systems and the first Linux exposure for countless users. RedFlag Desktop 11.0 was released after the brand’s revival, and it ships as a LiveCD — boot straight from a USB stick and try it without installing anything. It’s perfect for anyone curious about a domestic desktop OS without touching their disk partitions. Historical images like this are no longer easy to find through official channels, so a genuine source plus a verifiable hash matters more than ever.
