The sidewalks on the seafront promenade of Copacabana Beach are decorated with white and black pebbles in various wavy patterns, using mosaic blocks as paving materials, and the colors come from the natural white, black and cocoa brown. Especially from a high altitude, it is a series of continuous abstract patterns, which are naturally smooth and without repetition, and are also a sign here. And at the end of the day, it was quite lucky: in the evening, I met the most beautiful sunset and sunset in Rio de Janeiro, and the whole sky was reflected in a pink. This unique sunset I saw for the first time, very lucky. The trip for this day is quite satisfying. Although I feel a little tired during the driving process, I feel that all the effort is worthwhile at this moment.
