There are instructions on remittance fees on the websites of various banks, hehe, the People's Bank of China can't remit money.

CCB is similar to ICBC. Forget the postal service. Certainly not as fast as a bank.

There is no charge for ICBC's business in the same city, and 0.9% of the remittance amount is charged for business in different places, with a minimum of 1.8 yuan and a maximum of 45 yuan for each transaction.

If it is cross-regional and intra-provincial business, CCB is more favorable than ICBC. So you can send money directly to CCB. In terms of remittance, CCB is only cheaper or equivalent to ICBC, not more expensive than ICBC.

You can do the math.

Refer to the homepage of ICBC website, financial information charging standard module.
