Buckingham Palace (BuckinghamPalace) is the Queen's main bed and office in London. Its Royal Guard changing ceremony is an important project for London tours. Every year in 4-9 month, the Royal Guard of Buckingham Palace holds a change of guard every day in the morning, and every other month is held at 11:30 every two days. The change of guard ceremony has a strong sense of ritual and is very festive and beautiful, but unlike the Tiananmen Square class, it will attract a large number of tourists to watch and applaud.
