Why museums are returning cultural treasures
Summary
This is a painful love story about how museums should have cultural treasures.
It's because many people visit museums if a museum has rare and precious items. Thus curators have to collect those. 
However, do you have ideas where those rare and precious items came from?

Among those, there will be cultural treasures including tangible culture, intangible, knowledge, and natural heritage.
In the story, tangible items that are buildings, monuments, landscapes, books, works of art, and artifacts are shown. It is the legacy of physical artifacts from past generations, has to be maintained in the present, and has to be preserved for the benefit of future generations. However, it’s different between countries, races, and religion.

If races having cultural items are poor, they want to sell them to get money. In fact, from graves and even museums, items are stolen and sold.
If people find other religions properties, they think that those are enemies to break.
Archaeologists want to check those on how DNA are or past have, but those are stolen.
Museums want to collect rare treasures to be known by many people, however, if museums have things that are stolen, what do you think?
Even if there is a law, those will be battlefields that have different values.

Thus the speaker who has his museum returns cultural treasures.
