How many points can a chariot attack at once in xiangqi?
These answers restate the rules implemented by our open-source engine, which follows the WXF laws and is regression-tested against the official 110-diagram repetition casebook. Where an answer refers to a specific position, that position lives on the linked reference page, where the build verifies it against the engine before publishing.
Direct answer
On an empty board, up to seventeen points from a central position: eight along the rank and nine along the file. That count collapses fast in a real game, because the first piece in each direction, friend or enemy, stops the line there. A chariot's real reach is whatever is on the nearest four lines, not the theoretical maximum.
Counting the real number
Take each of the four directions separately and stop at the first occupied point. An open rank and a blocked file give a very different chariot from one hemmed in on both. This is why "the chariot is worth 9" is a starting point rather than a fixed number: a chariot with no line is a big piece doing nothing, as the piece-values discussion on the strongest piece in xiangqi explains.
Why the count matters practically
Before committing a chariot to a plan, count what it currently attacks and what it will attack after the move you are considering. A chariot swung to a fuller line for a single extra target is often worse than one left controlling four open points along an empty file.

Does a chariot's attack count change during the game?
Constantly. Every capture on its rank or file changes what it can reach, in either direction.
Is seventeen the same as a rook's count in chess?
Chess boards are smaller, so a rook's maximum is fourteen. The xiangqi chariot's extra reach comes from the larger 9x10 grid.
