According to the amount you want to apply for, you can ask the bank for a detailed understanding of your monthly income first. Then find out whether the income certificate that your unit can provide is enough. If it is enough, it is best. If it is not enough, try to open more income or attach other financial certificates, such as the ownership of the house and car. As for how to write the work certificate and income certificate, you can print it directly from the bank or ask the bank staff to help you write it, which is generally acceptable. Avoid writing back to the bank saying that the format and content do not meet the requirements.

I hope you go well ~
