A joke about miscalculation.

In this case, because of the calculation error, it is really troublesome. If you recalculate, it will take a lot of time. If you don't recalculate, the extra money is likely to be borne by yourself. So if you check out at ordinary times, you must be careful and take good care of our foreman. He records directly on the site record, and he records the working days directly for us, so don't worry too much about the rest.
