So, does the strategy of counterattacking in the center also apply to XiangQi?Not really. Because xiangqi lacks pieces that are strong on the diagonals, the center of the board is far less important, and in fact is almost insignificant compared to the center of the board in international chess.
Your counterattacks in xiangqi could be in the center, and will often be on the opposite flank, but could even be on a line adjacent to your opponent's thrust into your territory! It will depend on which open lines you can control to move your chariots forward, probably along with a cannon, and whether or not you have to shift those pieces east or west to better lines before moving forward. You'd usually like to have a horse across the river as well, and anticipating that path can influence the routes that your other pieces will need to use.
