Interesting documentary

I stumbled across an interesting documentary the other day covering a team of engineers trying to reconstruct the "Rainbow Bridge" according to Sung dynasty techniques.  Interesting not because of langauge instruction, but more with cultural exchange between some smart people from China, and smart people from the US.

The different personalities at times clash and represent your typical office characters.
