Transaction Level Translation
Next day they make another transaction and for that let us say the Chine Gove rate is 6.5 Yuan to a dollar so now they have a balabce of 6 + 6.5 = 12.5 Yuan in their books.
Now the corporate rate from Yuan to Dollar rate is say 6.12 yuan to dollar so when they translate the Yuan ledger to USD ledger they get 2.04 USD.
