Thanks. I know, we have had several Chinese visas before so we know the requirements. However, we heard from other travelers that the Chinese embassy in Mongolia sometimes has different requirements (like hotel bookings, transport proof into the country, etc) or even refuses to give a visa at all (even if you meet the requirements).
I want to know what the present situation is.

Please see the requirements for Chinese tourist visa on this website https://www.travelchinaguide.com/embassy/visa/tourist.htm
