How to test at the model of ganache-cli --fork

I am not sure whether I should ask at here.
I am trying to write an article about how to test contracts on the mainnet at the model of ganache-cli --fork, I can get free token from the unlocked account, but I can not interact with the contract on the mainnet, ganache-cli -f -u 0x07bb41df8c1d275c4259cdd0dbf0189d6a9a5f32.

Hi @Skyge - this article may help guide you; under their “easy way” instructions, it gives you information on how to use Ganache and Infura together to interact with the mainnet.

Thanks, I will look at it,
