Is it normal to receive accounts within 303,000 days across banks?

Is it normal to cross-bank 300,000 to arrive in three days? This is normal, because if the transfer of 300,000 yuan is inter-bank, the bank needs to call to confirm the transfer. Because this amount is huge, it is normal to ensure that there are no other problems in the transfer, so it is normal for the three-day transfer period to arrive.
