On an autumn day in 1967, Li Dafang, a native of Beijing, got out of a transport vehicle in the heartland of Inner Mongolia. The temperature was minus 40 degrees Celsius.
He was an intellectual banished there during the Cultural Revolution, and had to adapt to a new lifestyle which meant living in a yurt and tending horses.
But Li became so enamoured with the ways of the Mongols that he tries to return to those endless plains each year, and last month, after we were introduced through a mutual acquaintance, he invited me to go along with him.
It would be an experience far removed from the package tours with their obligatory wrestling bouts and horse-racing.
At midnight about 20 of us met in Beijing along with two Chrysler Jeeps and one mianbao che (a 'bread loaf van', so named because it looks like a loaf on wheels).
Our driver, Lao Zhou, drove for 13 hours, through Badaling, the most famous section of the Great Wall, and on the next day, to Xilin Hot, the second largest town in Inner Mongolia.
At lunch, we were given our first taste of something called Grasslands White Wine (Cao Yuan Bai Jiu.) This is some kind of mixture of raw alcohol and ammonia, I think, with a little leftover uranium thrown in for taste. It is, thankfully, served in thimble-sized glasses.
