In the .txt manual bundled with the game, some text is missing in the "Strategy" section. The correct version of that bit is as follows:

Openings:

There are many different openings in Chinese Chess. Whole volumes have been dedicated to this single facet of the game.

The most common opening is the "Central Cannon" opening. This consists of moving either Cannon directly behind the central pawn. Subsequently, the Knights may be moved out to defend the central Pawn in case the opponent decides to open similarly. Otherwise, the central Pawn can advance with little fear of being captured by the enemy Pawn because it would place the opposing King in check by the supporting Cannon.
