白金汉宫广场的巧遇

We were visiting Buckingham Palace in London on July 13, 2022 when the right door of Buckingham Palace opened.
Then four snow-white horses walked out with a convertible four-wheel vehicle . The horses are all pure white ones and look very noble. Compared with the other two convertible four-wheel vehicles running nearby meanwhile, pulled also by horses, those horses are all brown ones. Obviously contrasting!
