"象棋中的车" in English can be translated as "the Rook in Chinese chess" or simply "the Rook (in Xiangqi)".
Here, "Rook" is the standard term used in chess (both Western chess and Chinese chess/Xiangqi) to refer to the piece that moves straight horizontally or vertically. In Chinese chess (Xiangqi), the piece corresponding to the Rook is called "車" (pinyin: jū), but in English, it is conventionally referred to as the "Rook" when discussing the game in an international context.
