Showing off between relatives is a common social phenomenon, but if it is not controlled, it may cause unnecessary contradictions and unhappiness. Here are some ways to deal with relatives showing off: 1. Don't compare with relatives. Don't feel inferior or jealous because your relatives show off, and don't try to compare with your own achievements. Everyone's life has different experiences and values, so there is no need to compare them.

2. Stay calm. Don't get excited or angry if your relatives' ostentation makes you uncomfortable. Stay calm and don't let yourself get caught up in mood swings.

3. Listen and respect. Try to listen to relatives' ostentation, and don't interrupt or belittle their achievements. Respect their efforts and success.

4. Change the subject. If the ostentation of relatives makes you uncomfortable, you can change the topic appropriately and discuss other interesting topics, such as travel, food and culture.

5. Keep your distance. If the ostentation of relatives makes you feel uncomfortable, you can keep your distance and reduce the frequency of communication with them.

In short, we should be calm, respectful and rational when dealing with relatives' ostentation, don't compare or belittle their achievements, and don't let yourself fall into emotional fluctuations.
