How to ask the boss for an advance payment?

Make clear the purpose first, and then put forward the solution. First, clearly explain the reasons for your advance salary, and then propose solutions while asking for advance salary. For example, "Hello, boss! I'd like to discuss the salary increase with you. As there are some urgent family expenses recently, I hope to advance my salary for next month. I cherish this job very much and understand the company's regulations. I will make up this part of my salary as soon as possible. I hope you can consider my situation and give me your support. Thank you very much for your understanding and support. "
