Why are China cultural relics all over the world?

I think there are two main reasons why China's cultural relics are scattered all over the world.

The first reason is that in ancient times, although China's technology was not so developed, China also made friends with people from all over the country and abroad. It is not groundless to say that Yang Guifei went to Japan in the Tang Dynasty. It can be seen that China was connected with other countries at that time.

So at that time, it was not impossible for China to exchange cultural relics with foreign countries to show reciprocity.

Another reason is that Eight-Nation Alliance invaded Beijing at that time. At the end of the Qing Dynasty, due to the corruption and incompetence of the Qing Dynasty and the closed door at that time, China lagged far behind other countries.

So when all countries in the world have developed science and technology, and China is still in the most backward stage, they can only be bullied when they open their doors. At that time, Eight-Nation Alliance invaded Beijing together, burned the Yuanmingyuan and looted all the treasures in it. Everything that can be moved has been moved, and we can't. It was all smashed and finally burned.

After the Yuanmingyuan was burned down, Eight-Nation Alliance removed all the cultural relics from China, and they also auctioned them unscrupulously. So far, we haven't found all the constellations. So it is because of their brutality that China's cultural logistics has fallen all over the world, and its whereabouts are still unknown.
