How to use vm.load to get string value (given storage slot)?

[linghuccc]

In my solidity contract, there is a private string parameter (value already defined). I used "forge inspect" and found out that it is stored in Slot 9. I used vm.load to get the value of Slot 9 and it was 0x000000000000000000000000000000000000000000000000000000000000006d. This turned out to be a pointer, pointing to actual storage location.

Then I used vm.load to load value stored in 0x000000000000000000000000000000000000000000000000000000000000006d, it turned out to be 0x0000000000000000000000000000000000000000000000000000000000000000.

Why is this so? Isn't it supposed to be the pre-assigned string value?
