I don't want to practice in the company anymore. I want to send a message to my boss and edit a message.

The following points should be noted: 1. Interns are generally arranged by schools and enterprises. Therefore, when you don't want to continue your internship, contact the teacher first and then explain to the company. Otherwise, unilaterally interrupting the internship may affect your graduation; 2. If you are looking for an internship yourself, generally speaking, when you choose not to stay in the enterprise, you should find the corresponding department, such as the office or the personnel department, or find the person in charge of your department to explain the situation; If your company is small and you think only the boss can handle this matter, you can go to him directly. However, it is completely wrong for you to leave your job and end your internship by sending a text message. On the one hand, it will affect the signing and approval of your internship materials (most fresh graduates will send you some materials after entering the internship period, which will be signed and approved by the internship unit as an attachment to graduation procedures); On the other hand, if you unilaterally interrupt your internship and fail to follow the process, the small company will generally not pay your previous salary, and will also treat it as absenteeism. I hope you handle it carefully.
