For the average person, holidays are a day to relax or reunite with family. But for tourists, every holiday is a busier weekday. They stick to their posts, escort the journey of tourists, and also interpret the meaning of labor. Today is the "May Day" International Labor Day, maybe you have already packed your bags to start the journey, you might as well use a smile and encouragement to pay tribute to these tourists who silently stick to their posts!
