A museum day full of surprises

During the National Day trip to Italy, I unexpectedly enjoyed a wave of benefits in Rome, which is to visit the museum for free, because the first Sunday of each month is the free day of Rome's museum. Although without exception, they all have to queue for one or two hours, but after a day, in addition to the original plan of the Colosseum and St. Peter's Cathedral, an unexpected Capitoline Museum was added, which is considered a burst of luck.
