First, uneven quality will lead to frequent accidents.
Although everyone's quality is generally improving now, there are still a few people whose quality is really low. Many people in hegemony are people with extremely low quality. They don't realize their mistakes, and think that others have different opinions from themselves, which is someone else's problem, and they don't really look for the root of the problem from themselves. This is extremely unfavorable for error correction. Quality cannot be improved overnight. It needs to be corrected slowly and perfected slowly. Although it takes time, it should be allowed.
Second, the punishment for bullies is still too light.
Detaining people with low quality for seven days can't really change their behavior. If it is so serious that they can't continue to take the high-speed train for life, it will make this group of people feel a sense of crisis. I believe that many people will not do anything to dominate the seats. Now, if they really can't take public transportation such as high-speed rail, it can be said that they can't move, and it is impossible to drive everywhere. Even if I can, I don't have that much energy.
Bullying incidents occur frequently. First, people with low quality still exist. Second, the punishment for bullying is relatively light.
