There are also some small handicrafts, ornaments, mobile phone cases and the like. This kind of handicraft shop is very common in our country, and there are many on every street. Generally, China's enterprises in other countries sell clothes, shoes or restaurants, and there are fewer shops selling small handicrafts. You can focus on this aspect. And some DIY things. Print your favorite patterns on water cups, clothes and mobile phone cases; Hand-woven dolls, pendants and so on. These things must sell well abroad. Besides, handicrafts are a great traditional craft in China, and we can also take this opportunity to spread China culture.
Another thing is to open an "imported" snack shop. That is to say, open a shop selling China snacks in Brazil. You can sell some spicy strips, potato chips, French fries and the like from regular manufacturers. Consuls sell well in China and I believe they will sell well abroad.
In a word, you can do a lot of business in Brazil. As long as you have a good mind, business should be fine.
