There are many paintings in the National Gallery of Art in London that can be read or not listened to for a whole day. It also takes half a day. There are still a lot of big paintings in the gallery. There are also many famous paintings such as Leonardo Da Vincila Van Gogh Raphael La Monella and so on. I finally saw Sunflower and Water Lotus, though they are not the most famous ones. This kind of cultural attraction is also a very important part of tourism.
