i am mongolian. i want go brazil tourist. way need you.

I find that there is no embassy or consulate of Brazil in Mongolia, SO you may just try to apply for the visa from the Brazil Embassy in China. Generally, you need your passport, completely filled visa application form, and round-trip air ticket to apply for a Brazil tourist visa. However, you may be required to provide other documents, since you will apply for the visa in a thid country rather than your home country. Thus, you'd bettet contact the embassy directly to know about the relevant details.
