Baike has what seems like some basic instructions that have been reconstructed. It honestly from the description seems more like a modern board game than I'd expect -- a board with locations, different pieces that have different functions in those locations, and movements/actions constrained by dice throw results. Also is played 2-5, with 2 being best.
