Reminder: Using a Raspberry Pi connected to an ADS-B receiver in China and transmitting data to overseas platforms may violate the Counter-Espionage Law and the Data Security Law. There have already been cases where individuals were summoned by the National Security Agency for investigation.

It is not recommended to play with this in China. If you profit from it, you could face imprisonment, as it may violate the Anti-Espionage Law and the Data Security Law.
I personally know two stubborn friends who connected their Raspberry Pi to an ADS-B receiver and transmitted data over their home broadband public IP to FlightAware. Within less than two months, they were summoned by the National Security for a “tea chat”. The reason is that China Telecom deploys DPI identification on home broadband, even though these overseas platforms anonymize uploaders from Chinese IPs.
Therefore, real-time transmission and uploading of ADS-B data to overseas platforms (such as Flightradar24, FlightAware, etc.) is illegal. Domestically, there are no laws or regulations prohibiting private installation or reception of ADS-B signals. Uploading to platforms like VariFlight (Feichangzhun) is still in a gray area, and you may also be taken in for a “tea chat”.

It was discovered that the 'Limit IP Address Tracking' setting in iPhone's cellular network causes mihomo configuration to fail to use Apple Intelligence properly, because this setting has higher priority than the proxy tool, sending unencrypted DNS requests and other traffic directly to Apple servers, thereby exposing the Chinese IP and being denied service.
