If your relatives often come to dinner, you can consider the following ways to deal with it:

1. Direct communication: Talk frankly with your relatives about your troubles and let them know that you don't want them to come to dinner every day, and you can also discuss a suitable frequency.

2. Set a limit: If you don't want your relatives to come to dinner every day, you can set a limit, such as once a week or once a month.

3. Set a meal time: You can set a meal time to let your relatives know when you eat and let them leave at the right time.

4. Offer takeout: If you don't want to cook in person, consider offering takeout, or suggest that your relatives go out to eat by themselves.

5. Find alternatives: If you don't want your relatives to eat, you can consider providing other alternatives, such as letting them go to a restaurant or inviting them to eat elsewhere.

No matter which way you take, you should try to be polite and respectful to avoid hurting the feelings of your loved ones.
