Re margarine and butter prices here, I have no idea. I stopped eating them when I first reached China, years and years ago. They weren't available in Shanxi then. No supermarkets in Yuci at that time!

Can't help, sorry!

At that time, got off the plane at Beijing Airport. Got on an airport bus to take the short journey to the main airport building. Took a three-wheeled putt-putt vehicle from the airport to the city! (Sat beside the college FAO).

How times have changed!
