The Rainbow Bridge, located in the Niagara Falls area, is the border bridge between the United States and Canada near the "American Falls". The rainbow bridge is named a rainbow, and it is a rainbow in itself. It is only one aspect of the rainbow. There are many bridges in the world that are similar to this one. When the climatic conditions and angles are suitable, the rainbow formed by the water mist of the waterfall can be seen from the Canadian side, which may be the reason for the name of the rainbow bridge. If you take the cruise to a certain angle, and the sun and water mist conditions are suitable, you can be lucky to see double rainbows. I saw double rainbows. The rainbow bridge is a daily traffic. The United States and Canada have set up checkpoints near their bridgeheads to check people and cars in transit. I flew from the United States to Toronto, then to Niagara Falls, a few days later through the Rainbow Bridge from Canada into the United States, after visiting the American Falls Park area, then went to Buffalo City... On the Canadian shore and the United States shore to see the Rainbow Bridge, the landscape is different; While watching the second shore on the rainbow bridge, the angle is different, and the landscape is naturally different. I once walked on the Canadian side one night, under the bridge hole of the bridgehead pier of the rainbow bridge. It is different to see the bridge at night and the bridge during the day. The closest thing to seeing the rainbow bridge from the outside is to take the "horn" cruise ship, which is also my favorite observation of the rainbow bridge. In fact, the scenery did not move there, it was people moving, different angles. The life process, different positions, different periods, perception, attachment are also different. There may be some relative recognition of the natural landscape; but in human society, it is difficult to hope for the same and similar; if you want harmony, seeking common ground and seeking common ground in differences is to strive for as much as possible. Last time I mentioned: it is not that I only talk about the wind and the moon. In fact, I speak a little bit of ideas and ways of thinking in most of the words I write. I focus on republicanism, harmony and difference. I feel that the crux of many problems lies in thinking and culture. The road to changing cultural thinking is long. Human beings must have common points, including human life, human values, human freedom, and common points in human feelings, and these common parts have no inevitable relationship with national conditions, regions, history, and habits. Some people have suggested that there are common points, there are differences... so it is not necessarily related to the historical habits of the national conditions and regions. When I say that there are some common points among mankind, I mean these commonalities, not characteristics. The great unity of mankind and the happiness of mankind do not lie in merely stressing differences, but in striving for a republic. The so-called republic, which is different from one another, seeks common ground and exists different. The essence of seeking common ground and living apart is to be inclusive of the "different points" that cannot be solved for a while, and constructively maintains and expands the "same points". The Rainbow Bridge is essentially no different from other bridges, just because the two shores are artificially divided into two countries, so it becomes a border bridge. If there is no country, how free to walk! For example, we talk about love, two sides or one side preset a position that cannot be crossed. For example, the rainbow bridge, I hope that the other party will come, but I will not move, then I will never meet on the bridge, and I will never see a certain scenery.
