In August, I only went to Brazil, Sao Paulo, Rio, Iguazu and Curitiba, for a total of 10 days. It feels similar to that in China, and the public security is not as chaotic as advertised. But when traveling abroad, it is best to travel together. Now that society is developed, people's simple ideas have been eroded. Although Brazilians are enthusiastic and have many tourist attractions, they should pay attention to safety, especially the valuables, travel documents and wallets they carry with them. Moreover, the domestic promotion of hotels in Brazil is not as good as that in disposable goods, and the washing and tracing items are all brought by ourselves, which is actually not the case. Generally, hotels will provide towels, bath towels, soap, hair dryers, razors and skin care products. Just no toothpaste, toothbrush, shampoo and bath wave.
