My niece came to see me. How to talk about high emotional intelligence?

Say something like welcome first (for example: XXX, you are here, welcome, come in and sit down, come in and sit down ...)

Then say something like gratitude (for example, thank you for coming all the way to see me and always remembering me ...)

Then I say some common things, and greet my niece and her family about their health, work and study.

Finally, when saying goodbye, say goodbye and welcome my niece and her family to visit at any time.
