Why did BYD send a text message twice to confirm the normal resignation salary? The salary is different.

Accounting error. For employees who resign normally in BYD, the company's finance department will conduct salary accounting. After the accounting is completed, a salary confirmation message will be sent to the resigned employees. After confirmation, accounting will be carried out again to avoid accounting errors. If mistakes are found in the second accounting, it will issue salary confirmation again in a short time.
