Authentication of foreign documents for Chinese visa application

I was granted a grant to China and I was studying the Chinese language. There will be five papers, the first in which the data will be written in the mother tongue, the second in the Chinese language, and the other unit in which the place of work or the grant is written for the duration of the recruitment from abroad and the type of visa required and all the job data required from the Chinese party and the fourth written for a Chinese travel in your country In the Chinese language to make sure of the parties involved in the matter, and the last one writes in it the work contract and conditions in the Chinese language and receives copies of the travel of your country of origin and the country of recruitment,
But those are the conditions of my country, and I am not sure that it is the same in the United States of America
