Why can't overseas users directly access domestic platforms?

Domestic video platforms (Bilibili anime section, Youku, iQiyi) and music platforms (NetEase Music, QQ Music) are restricted to mainland China due to copyright agreements. Additionally, some financial apps (banks, Alipay) also restrict overseas IP logins.

What is the difference between split routing and global proxy?

Global proxy routes all traffic through back-to-China nodes, which slows down access to overseas websites. Split routing mode only routes domestic traffic through back-to-China lines, while overseas traffic remains direct or uses overseas proxies, balancing speed and domestic content access.

What is IPLC back-to-China routing?

IPLC (International Private Leased Circuit) is an international dedicated line that does not go through the public internet, offering low latency, high stability, and immunity from GFW interference. It is suitable for users with high requirements for back-to-China speed and stability, but is relatively expensive.

Is ClashX back-to-China split routing configuration complicated?

Not complicated. You only need to add back-to-China nodes and split routing rules to the ClashX configuration file. This tutorial provides a complete YAML configuration template that you can copy and paste, then modify the node information. The entire configuration process takes about 10-15 minutes.

ClashX Back-to-China Split Routing Configuration Tutorial [2026] Complete Guide for Overseas Access to Domestic Content

Q: What is back-to-China routing?

Back-to-China routing refers to overseas users connecting to proxy servers in mainland China to obtain a mainland China IP address, thereby bypassing geographic restrictions on domestic platforms and accessing content and services limited to mainland China users, such as Bilibili, Youku, iQiyi, and NetEase Music.

Q: What should I do if back-to-China node speed is slow?

Suggestions: 1) Choose IPLC or CN2 GIA line airports; 2) Select the entry node closest to your physical location; 3) Enable url-test in ClashX to automatically select the node with the lowest latency; 4) Avoid peak hours (Beijing time 20:00-23:00); 5) Check if your local network has bottlenecks.

Why You Need Back-to-China Split Routing?

If you are a Chinese living overseas, an international student, or a business traveler, you must have encountered these problems:

                                Bilibili Anime: "Sorry, this content is not available in your region"
Youku/iQiyi: Many TV shows and movies are only available in mainland China
NetEase Music/QQ Music: Licensed songs are grayed out and unavailable overseas
Douyin: Overseas IPs are automatically redirected to TikTok international version
Bank Apps: Some operations are restricted for overseas IPs with "abnormal network environment" warnings
WeChat/Alipay: Some features (red packets, wealth management) are IP-restricted

                            

The root cause of these restrictions is copyright geographic licensing and financial compliance requirements. Content providers' copyrights only cover mainland China, and financial institutions need to ensure users operate from compliant regions.

What is "Back-to-China Routing"?

Opposite to breaking out from mainland China, "back-to-China routing" refers to overseas users connecting to proxy nodes in mainland China to obtain a mainland China IP address, thereby accessing geographically restricted domestic content and services. ClashX's split routing feature allows you to access both domestic and overseas content simultaneously without manual switching.

Back-to-China Split Routing vs Global Proxy

Many users' first instinct is to "just use global proxy with back-to-China nodes," but this approach has obvious problems:

Global Proxy

❌ Not Recommended

Split Routing Mode

✅ Recommended

Problems with Global Proxy

Google, YouTube, Netflix and other overseas services become slow (need to route out of China)
Accessing overseas websites adds an extra hop, increasing latency by 100-300ms
Back-to-China bandwidth is limited, wasted on traffic that doesn't need it
Some overseas services block Chinese IPs

Advantages of Split Routing Mode

Domestic traffic (Bilibili, NetEase Music, etc.) → routes through back-to-China nodes
Overseas traffic (Google, YouTube, etc.) → direct connection or overseas proxy
Best of both worlds, optimal speed
Back-to-China bandwidth only used for traffic that truly needs it

Back-to-China Node Selection Guide

The quality of back-to-China nodes directly determines whether you can watch Bilibili in 4K smoothly. Here are the main types of back-to-China lines:

Rule Priority

ClashX rules are matched from top to bottom, with the first matching rule taking effect. It's recommended to put the most frequently used domain rules at the top and GEOIP at the bottom as a fallback. For more rule details, refer to the TUN Mode Tutorial.

DNS Split Routing Configuration

DNS split routing is key to a good back-to-China experience. If domestic domains are resolved by overseas DNS, they may return overseas CDN nodes, causing slow speeds even with back-to-China routing.

DNS Split Routing Configuration

dns:
  enable: true
  enhanced-mode: fake-ip
  fake-ip-range: 198.18.0.1/16
  nameserver:
    # Use overseas DNS by default
    - https://dns.cloudflare.com/dns-query
    - https://dns.google/dns-query
  fallback:
    - https://1.1.1.1/dns-query
    - tls://8.8.4.4:853
  fallback-filter:
    geoip: true
    geoip-code: CN
  # Use domestic DNS for domestic domains
  nameserver-policy:
    "+.bilibili.com": "https://doh.pub/dns-query"
    "+.bilivideo.com": "https://doh.pub/dns-query"
    "+.youku.com": "https://doh.pub/dns-query"
    "+.iqiyi.com": "https://doh.pub/dns-query"
    "+.music.163.com": "https://doh.pub/dns-query"
    "+.qq.com": "https://doh.pub/dns-query"
    "+.taobao.com": "https://doh.pub/dns-query"
    "+.jd.com": "https://doh.pub/dns-query"
    "+.baidu.com": "https://doh.pub/dns-query"
    "+.weibo.com": "https://doh.pub/dns-query"
    "+.zhihu.com": "https://doh.pub/dns-query"
    "+.alipay.com": "https://doh.pub/dns-query"
    "+.douyin.com": "https://doh.pub/dns-query"

nameserver-policy ensures domestic domains are resolved using Tencent DNSPod (doh.pub, returning the optimal domestic CDN node IP, combined with back-to-China routing for best speed.

Common Use Cases

Scenario 1: Watching Bilibili Anime Overseas

Many Bilibili anime are only available in mainland China. After configuring split routing, traffic to bilibili.com automatically routes through back-to-China nodes, and the anime section no longer shows "region restricted" messages. IPLC lines are recommended for smooth 4K playback.

Scenario 2: Listening to NetEase Music Licensed Songs

About 30% of NetEase Music songs are grayed out overseas due to copyright issues. Split routing configuration directs music.163.com to back-to-China nodes, making grayed-out songs playable again.

Scenario 3: Normal WeChat Pay/Alipay Usage

Some financial operations detect IP regions. Through back-to-China split routing, WeChat red packets, Alipay wealth management and other features work normally without "abnormal network environment" warnings.

Scenario 4: Accessing Domestic Bank Apps

Some functions in bank apps like ICBC and CMB are restricted for overseas IPs. Back-to-China split routing makes bank apps think you're in China, allowing transfers, inquiries and other operations to proceed normally.

Scenario 5: Using Douyin Instead of TikTok

Overseas IPs accessing Douyin are redirected to TikTok international version. After configuring split routing, douyin.com routes through back-to-China lines, allowing normal use of the domestic Douyin version.

Verify Configuration is Working

After configuration is complete, verify using these steps:

                                Check IP: Visit ip.sb or myip.ipip.net to confirm a mainland China IP address is displayed
Test Bilibili: Open Bilibili's anime section, select an anime marked "mainland only," and confirm it plays
Test NetEase Music: Search for a previously grayed-out song and confirm it plays normally
Check ClashX Logs: In ClashX's connection panel, confirm that bilibili.com and other domains are routing through back-to-China nodes
Test Overseas Websites: Simultaneously access Google to confirm overseas websites still work normally and speed hasn't decreased

                            

Frequently Asked Questions

Q: Can back-to-China nodes and overseas proxy nodes be used simultaneously?

A: Yes. This is exactly the advantage of ClashX split routing. You can configure both back-to-China node groups and overseas proxy node groups simultaneously, with different domains using different lines. For example, bilibili.com uses back-to-China routing while google.com uses overseas proxy, without affecting each other.

Q: What should I do if back-to-China node speed is slow?

A: 1) Switch line types, IPLC > CN2 GIA > BGP; 2) Use url-test groups to let ClashX automatically select the fastest node; 3) Avoid peak hours (Beijing time 20:00-23:00); 4) Contact your airport's customer service to confirm back-to-China lines are working properly.

Q: Bilibili still shows region restrictions after configuration?

A: 1) Clear Bilibili cache and cookies; 2) In ClashX's connection panel, confirm bilibili.com is indeed routing through back-to-China nodes; 3) Check if DNS is correctly split (domestic domains should use domestic DNS); 4) Try switching different back-to-China nodes.

Q: Do I need to enable TUN mode?

A: System proxy mode is sufficient for browser access to Bilibili, NetEase Music and other websites. If you need domestic apps (like WeChat, Alipay desktop version) to also route through back-to-China lines, you need to enable TUN mode.

Q: Which airports provide back-to-China nodes?

A: Not all airports provide back-to-China nodes. Before purchasing, confirm whether the airport has nodes labeled "back-to-China," "mainland China," or "China Mainland." Some airports specializing in back-to-China services provide IPLC back-to-China dedicated lines.

Q: Will back-to-China split routing affect overseas website speed?

A: No. In split routing mode, only traffic matching domestic rules routes through back-to-China nodes; other traffic remains direct or uses overseas proxies. The two lines don't affect each other.
