A closer look at the network, protocols and perks behind Qingyu's proxy subscription service.
Everything below is part of the base subscription — no separate add-ons required to reach full speed.
Core traffic runs over dedicated BGP backbone lines rather than shared, oversold routes, which keeps latency and jitter low even when regional networks are congested.
Higher tiers route through IEPL (International Ethernet Private Line) capacity for an even more direct, less congested international path, particularly useful for large uploads and live streaming.
AnyTLS is a newer, TLS-based protocol designed to blend in with ordinary encrypted web traffic while remaining fast and simple for client apps to configure.
Shadowsocks remains one of the most widely supported proxy protocols, with mature client apps available on every major desktop and mobile platform.
Configuration options are also compatible with V2Ray-based clients, giving more advanced users flexibility in how they route and manage their connection.
Every plan supports up to five simultaneous devices, covering a laptop, a phone, a tablet and a home streaming box on a single subscription.
Recurring plans reset their full data allowance every month, and one-time no-expiry data packs are available separately for occasional top-ups.
A dedicated line profile is tuned specifically for TikTok and cross-border e-commerce workflows, aimed at overseas sellers managing storefronts and ad accounts.
Independent connection testing around Qingyu's network reports reliable access to major global platforms including Netflix, Disney+, Amazon Prime Video, Spotify, TikTok and the US catalog of YouTube Premium.
The combination of dedicated line capacity and protocol choice (AnyTLS or Shadowsocks) is what keeps '秒开' — instant playback — realistic on higher-tier plans rather than a marketing claim, particularly for 4K and 8K sources during peak evening hours.
Because plan tiers scale from Bronze up to Diamond by monthly data allowance rather than by feature-gating, every subscriber gets the same protocol and streaming access — heavier plans simply provide more headroom.
ChatGPT, Claude and Gemini all rely on a stable, low-latency connection to feel responsive — a flaky connection shows up as stalled responses, dropped sessions and repeated sign-ins that break your workflow.
Qingyu's dedicated line routing is designed to keep these AI sessions stable throughout the day, which matters for remote workers, developers and content creators who treat AI assistants as a core part of their toolkit rather than an occasional convenience.
The same stability benefits video calls, cloud IDEs and other latency-sensitive remote-work tools that foreign-trade and freelance professionals depend on daily.
AnyTLS is a newer protocol built to resemble ordinary TLS-encrypted traffic while staying fast to configure, while Shadowsocks is an older, extremely widely supported protocol with mature clients on every platform. Qingyu supports both so you can pick whichever your client app handles best.
IEPL stands for International Ethernet Private Line — a dedicated, point-to-point international connection instead of a shared public route. It generally offers lower latency and more consistent throughput, which higher-tier Qingyu plans route through for streaming and large transfers.
Yes, every plan supports up to five devices connected simultaneously, so you can cover a laptop, phone, tablet and a streaming box from a single subscription.
Yes — a dedicated line profile is tuned for TikTok and cross-border e-commerce workflows, which is one of Qingyu's core user groups alongside streaming and AI-focused users.
