The approval time of general bank loans is about 15 days. If there is a policy change, the time may be extended to 1 month. Or the bank is short of money. At this time, loans may need to be queued, and the time will be further extended.
If it has not been approved for more than 3 months, it may be that your materials or qualifications do not meet the loan conditions. In case you can't handle it, the bank will also inform you.
