What should you say when you make a vlog to introduce yourself? How is the language used in the vlog?

When making a vlog to introduce yourself, you should ideally cover the following points:

1. **Your background information**: Share where you’re from, your education, and any relevant life experiences.
2. **Your qualifications**: Highlight your academic achievements or certifications relevant to the content of the vlog.
3. **Your relevant experience**: Discuss any previous work, projects, or experiences that are pertinent to what you’re vlogging about.
4. **Why you should be chosen**: Explain what makes you a good fit for the content or purpose of the vlog.
5. **Your bad habits**: It's generally not necessary to include this, as it may detract from a positive introduction.
6. **You don't need to mention your parents' names or contact details**, as this information is usually private and not relevant for a public introduction.
7. **Your opinion about the company or university**: If relevant, focus on positive aspects; critical comments might not be conducive to a favorable impression.

As for the language used in the vlog, it is typically **informal**. This style helps create a personal connection with the audience and makes the content more engaging. Use a conversational tone, and feel free to express your personality while remaining clear and coherent.
