Do i need to apply Visa in Russia? If so, what are the requirements?

Ann, according to the website of Chinese embassy in Russia, foreigners from other countries can apply as long as they have valid legal status or entry permit to Russia. But I still suggest you confirm this with the consular department. The required documents are your passport, finished application form affixed with a recent passport photo, flight ticket out of mainland China and hotel booking.
