Is there a xiangqi equivalent to chess's idea of a bad bishop, a piece hemmed in by its own structure?
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
The idea exists, even though xiangqi commentary doesn't use that exact chess phrase. The closest parallels are a cannon stranded with no useful screen anywhere on its lines, or a chariot boxed in behind its own soldiers and advisors with no open file to use. Both describe a piece that is nominally strong on paper but genuinely doing very little because of how its own side's structure has developed, exactly the underlying idea a "bad bishop" captures in chess.
Why the cannon fits the comparison especially well
A chess bad bishop is hemmed in by its own pawns sitting on the wrong-coloured squares; a stranded xiangqi cannon is hemmed in by its own side having nothing useful sitting on its lines to act as a screen. In both cases the piece's raw movement is not the problem, its actual usefulness given the surrounding structure is.
Why a boxed-in chariot is the other common version
Since a chariot's whole value comes from open lines, one stuck behind its own undeveloped pieces with no file to use is doing almost nothing despite being the strongest piece type in the game, a very similar underlying problem to a chess piece that looks powerful yet contributes little in practice.

Is there a specific Chinese term for this idea?
Not one single fixed phrase the way "bad bishop" is fixed in English; it is usually just described directly as a piece with no targets or no lines.
Can this be fixed the same way a bad bishop sometimes is, by trading it off?
Often yes, though reactivating it by opening a line or clearing a screen is frequently the better plan if there's time for it.
