Features
Explore the core features and technology behind Feiyu VPN for China
Next-Generation WireGuard Protocol
Feiyu VPN for China fully adopts the WireGuard protocol, which uses only 4,000 lines of code (compared to OpenVPN's 600,000) while delivering 3-5 times the transmission speed. This streamlined code reduces the attack surface and enhances security, allowing you to enjoy extreme speed without concerns about privacy breaches.
Audited No-Logs Policy
Feiyu VPN for China implements the strictest no-logs policy in the industry—no recording of connection times, websites visited, IP addresses, or any browsing data. This policy has been independently audited by the renowned security firm Cure53, with a comprehensive report published to ensure every promise stands up to scrutiny.
Millisecond Intelligent Connection
Feiyu VPN for China's intelligent routing engine continuously monitors the latency and load of global nodes, automatically matching you to the optimal path. One-click connection with latency as low as 15ms delivers a seamless experience for video conferencing, online gaming, or 4K streaming.
Coverage in Over 80 Countries
Feiyu VPN for China has deployed over 3000 high-speed servers across more than 80 countries and regions, including North America, Europe, Asia-Pacific, South America, and the Middle East. Each server operates in pure RAM mode, ensuring all data is wiped upon reboot, eliminating any chance of data retention at the hardware level.
One Account, 6 Devices Online Simultaneously
With one Feiyu VPN for China account, you can protect your smartphone, computer, tablet, smart TV, and router simultaneously—allowing up to 6 devices to connect at once, so your entire family can share a secure network without extra fees. After configuring the router, you can even protect IoT devices that don’t support VPNs.
24/7 Professional Customer Support
Feiyu VPN for China has a bilingual customer service team fluent in Chinese and English, providing 24/7 online support. Whether it's installation, connectivity issues, or account management, you can receive immediate, professional assistance via live chat or email, with an average response time of under 2 minutes.
In-Depth Analysis of Protocol Technology
Discover how the cutting-edge tunneling protocol employed by Feiyu VPN for China provides you with unmatched speed and security.
WireGuard Core Architecture
Feiyu VPN for China has built a new tunneling engine based on the WireGuard protocol. WireGuard achieves full VPN functionality with approximately 4,000 lines of code, while traditional OpenVPN requires over 600,000 lines. The streamlined code results in a smaller attack surface, lower latency, and higher throughput. In our internal tests, the handshake speed of the WireGuard protocol is 3 times faster than IKEv2 and 8 times faster than OpenVPN.
Noise Protocol Framework Encryption
Feiyu VPN for China's implementation of WireGuard utilizes the Noise protocol framework for key exchange, employing Curve25519 for ECDH key agreement, ChaCha20-Poly1305 for symmetric encryption, and BLAKE2s for hashing. This combination of cryptographic primitives has been widely validated by academia and industry, providing forward-looking security against quantum computing attacks.
Smart Protocol Switching
In certain network environments, WireGuard's UDP traffic may be restricted. Feiyu VPN for China includes a smart protocol switching feature that automatically detects network conditions and seamlessly switches between WireGuard, IKEv2, and our proprietary obfuscation protocol to ensure stable connections in any setting. The entire switching process is completed within 500 milliseconds, often imperceptible to the user.
Multi-Hop and Split Tunneling
Feiyu VPN for China supports multi-hop connections, allowing data to be relayed through two or more VPN servers, providing additional layers of privacy for users requiring extreme anonymity. Meanwhile, the split tunneling feature lets you choose which applications connect via the VPN and which go directly through the local network, achieving the best balance of performance and security.
Encryption and Privacy Protection
Multi-layer encryption technology and strict privacy policies to comprehensively protect your digital life.
AES-256-GCM Encryption Standard
Feiyu VPN for China utilizes AES-256-GCM encryption mode to secure all transmitted data. AES-256 is the encryption standard approved by the U.S. National Security Agency (NSA) for protecting 'top secret' information. Even using the most powerful supercomputers available, it would take billions of years to crack. Each connection generates a unique session key, ensuring forward secrecy.
DNS Leak Protection
Feiyu VPN for China operates its own private DNS server cluster, and all DNS queries are resolved through encrypted tunnels, eliminating the risk of DNS leaks. We also include WebRTC leak protection and IPv6 leak protection to ensure that your real IP address is never exposed. You can check your protection status at any time using the built-in leak testing tools.
Kill Switch
Feiyu VPN for China's network lock feature (Kill Switch) immediately cuts off all internet traffic if the VPN connection unexpectedly drops, preventing any data from leaking in an unencrypted state. This feature supports both system-level and application-level modes: the system-level mode protects all traffic, while the application-level mode protects only specified applications, providing maximum flexibility for users.
RAM-only Pure Memory Servers
All of Feiyu VPN for China's 3000+ servers operate in pure RAM mode. This means there are no hard drives on the servers, and all data is processed solely in memory. Each time the server is rebooted, all data is completely cleared. Even if a server is physically seized, no user data can be extracted. This represents the highest level of data protection in the industry.
Streaming and Entertainment Optimization
High-speed connections specially optimized for streaming and online entertainment, allowing you to enjoy global content seamlessly.
4K Ultra HD Streaming Support
Feiyu VPN for China's high-speed nodes are specially optimized to stably support the transmission demands of 4K Ultra HD (2160p) video streams. Whether it's HD movies, live sports events, or music videos, Feiyu VPN for China offers a stable, smooth, and buffer-free viewing experience. Under gigabit broadband, connection speeds can consistently exceed 500Mbps.
Gaming Acceleration and Low Latency
Feiyu VPN for China has been specifically optimized for online gaming. Our intelligent routing engine can automatically choose the path with the lowest latency to game servers. In our testing, latency to Asia-Pacific game servers was as low as 10ms and as low as 60ms to North American servers. DDoS protection prevents you from being attacked during gameplay.
P2P and Torrent Download Optimization
Feiyu VPN for China has enabled P2P optimization features on nodes in over 30 countries worldwide. We do not limit bandwidth or speed for P2P protocols like BitTorrent, while protecting your downloading activities from ISP monitoring and throttling through encrypted tunnels. The port forwarding feature improves seeding efficiency and supports faster upload speeds.
Smart Content Acceleration Technology
Feiyu VPN for China's proprietary SmartRoute technology intelligently identifies the type of content you are accessing and automatically selects the optimal transmission path. It automatically switches to streaming-optimized nodes while watching videos, to high-bandwidth nodes when downloading files, and prioritizes low-latency nodes while browsing the web. The entire process is fully automated without manual intervention.
