From the Ulaanbaatar Post:

Th Moscow Circus has not performed in Mongolia for over 25 years... However, that will soon change when the troupe form Moscow hits Ulaanbaatar to produce a week-long series of twice-daily shows between January 15 and 21 at Mongolia's State Circus...

Whilst the Russian performers who are on their way to Mongolia will not have too much problem with the winter temperatures, the elephants originate in India and are not used to the cold in Ulaanbaatar. To keep them warm Zorigt revealed that they are being given two liters of vodka per day.

Is that all? The Russian performers must be drinking them under the table.
