This question is a bit off-topic, but I can guess the core meaning—when withdrawing funds from a major exchange to a US account, could it trigger issues with overseas income reporting and taxation?

My understanding is that there are actually several layers behind this. First and foremost: there is no CRS agreement between the US and China. What does this mean? Whether you are transferring USD from a major exchange or other platforms to a local US bank, even if you register and open an account with a Chinese passport, the banking system will not automatically report information to tax authorities in both countries. Technically speaking, there is no automatic exchange mechanism for financial intelligence between the two countries. But this is just a technical fact; it does not mean there are no other risks, which is something that needs to be clarified.
