How much does it cost to travel to Bolivia?

Generally speaking, it takes about 50 hours to start from Guangzhou, pass through Doha and Sao Paulo, Brazil, and arrive in Santa Cruz, Bolivia after two connecting flights. The air ticket price in February next year is about11000-12000 (one-way). Even if12000 plus one night's accommodation, the round-trip air ticket cost will be about 25,000. It is about 900 kilometers from Santa Cruz to uyuni. Of course, you can also choose to fly from Santa Cruz to La Paz and then to uyuni, but it may cost more. If you rent a car, it is estimated that 1000- 1500, round trip 3000. So the toll is about 28,000 yuan, depending on how long you want to play. The accommodation fee is estimated to be around 35 thousand, which should be about the same. But what I am most curious about is how to get a visa, whether I need a transit visa from Brazil and so on. It is estimated that it will be more troublesome. I hope it helps.
