What do you mean by money and remittance? I hope it can be said in a popular way.

"Money" means cash, which means money.

"Foreign exchange" refers to the credit certificate and payment certificate expressed in foreign currency and used for international settlement.

Generally speaking, foreign exchange refers to the means of payment expressed in foreign currency that can be used for international settlement. In this sense, only foreign currency funds deposited in banks and foreign currency bills that concretize bank deposit claims constitute foreign exchange, mainly including bank drafts, checks, bank deposits, etc.
