When encountering someone occupying a seat, we can take the following steps to deal with it:

1. Stay calm: First, whether on the high-speed rail or elsewhere, face the situation where someone is occupying the seat. phenomenon, we should remain calm and rational. Emotions or conflict will only exacerbate the conflict, so we should stay calm and look for ways to solve the problem.

2. Ask politely: If I see someone occupying a seat, I will politely walk up to them and ask them if they can free up their seat for someone who needs it. You can say: "I'm sorry, could you give up your seat to the person who needs it?"

3. Seek help from others: If asking politely doesn't work, I will try my best to ask for help from others. The situation can be reported to train staff or the conductor and requested to intervene and resolve the problem. They will usually take appropriate measures to ensure fairness and order.

4. Provide alternative seats: If there are no other empty seats around, I will proactively provide other alternative seats to those who need them. This will not only help those who need a seat, but also inspire others to reflect on their actions through their own actions.

5. Advocate public order: Domineering behavior is an uncivilized behavior. We can change this phenomenon by advocating public order and etiquette. When appropriate, you can share your opinions through social media or other channels to remind others to respect the rights of others and maintain good social order.

6. Support relevant policies: The government and enterprises should also take corresponding measures to deal with the problem of seat dominance. For example, strengthen publicity and education to improve public awareness and literacy; increase law enforcement and punish violators; improve seat layout design and provide more barrier-free seats, etc. We can support and participate in the implementation of these policies and measures, and jointly build a civilized and orderly social environment.

To sum up, when faced with seat dominance, we should remain calm, politely ask others if we can give up our seats, and seek help from others. At the same time, we should also take the initiative to provide alternative seats and solve this problem by advocating public order and supporting relevant policies. I believe that only by working together can we create a more civilized and harmonious social environment.
