1. Apply for a Hong Kong card through Hong Kong (there are many online tutorials, it's very simple, and currently not strict, with almost no cost except travel expenses); if you don't go to Hong Kong, after opening a mainland card at a Hong Kong/foreign bank in mainland China, find a customer manager to apply for a Hong Kong card with lawyer's witness (for example, deposit 500,000 in HSBC to apply for a Premier Wealth Management Card; you can call each bank to inquire about their requirements).

2. USDT/USDC -> Compliant exchange Kraken -> Compliant exchange platform Wise -> Alipay/bank.

Required materials:

1. Passport; 2. ID card; 3. Proof of address; 4. Tax records; 5. Labor contract; 6. Recent photo.

The most difficult part may be the proof of address. If you have a credit card, it's simpler; if not, ask the neighborhood committee/village committee for a stamped proof of residence.

3. Exchange cryptocurrency for Hong Kong dollars or Renminbi through trading platforms or exchange points in Hong Kong. This usually requires a personal visit to Hong Kong, and it is advisable to withdraw in small amounts multiple times to reduce risk.

4. Through banks in Singapore or Hong Kong: transfer funds from Coinbase or Hashkey HK to bank accounts in these regions, then transfer to Alipay or mainland bank cards.

5. Choose Binance insured merchants for withdrawals, and be sure to select merchants with adequate protection.
