The above route is the slowest. As long as any link only uses PBOC's payment system, it will generally arrive the next day or even the same day.
But the actual situation is often that every Chinese bank has to charge a handling fee (generally 1%) for cross-bank remittance in different places, but they remit money according to ordinary remittance, so that's why you have to wait five days to receive the money.
It is precisely because the network is not as huge as Chinese banks, so now foreign banks will use PBOC payment system, which is much faster than Chinese banks, and friends around them have a deep understanding.
