Common Support Questions

筑基 Foundation Building (300 GB, up to 500 Mbps) covers most daily streaming, browsing, and remote-work usage comfortably. Heavier users who stream in 4K regularly or transfer large files should consider 金丹 Golden Core instead.

First confirm the client supports the Reality protocol (Surge and Quantumult X do not). Then check that you've selected a node on the carrier route that matches your own ISP — using an Unicom-optimized node on a Telecom connection, for example, will underperform.

Yes — the carrier-aware routing simply reflects which network you're currently on. If your ISP changes, reconnecting will resolve to the best-performing path for the new network automatically.

Refund and trial policies are set by the underlying CTC2 service itself, not by this informational site. Check the current terms on the plan page you reach through the Get Started button before subscribing.

Our support team typically replies within one business day during posted support hours. For account-specific issues tied to an active subscription, the fastest path is usually the support channel listed on your subscription provider's own page.

What We Can Help With

This site exists to explain CTC2's technology in plain language — the difference between direct connection and relay-based proxies, how carrier-aware routing picks a path for your ISP, and which client apps actually support the Reality protocol. If you're stuck deciding between 练气, 筑基, and 金丹, tell us roughly how much data you use per month and what you stream, and we can point you to the right tier.

We can't manage an active subscription, process a refund, or reset a login on your behalf — those actions happen on the actual CTC2 platform, not here. What we can do is make sure you understand exactly what you're subscribing to before you get started, and help you troubleshoot common client-side configuration mistakes once you have a subscription URL in hand.
