Thanks for a so-quick verification! Look like those numbers are “safe” enough to post on CPW too

Re: Chinese chess Xiangqi perft results
Had a quick look at your rule set implementation, I don't think it is right. Repetition is not always lost for the playing side, for example, this is a trivial draw:

Some other exotic examples:
4kr3/9/5c3/5R3/9/4C4/9/9/6n2/5K3 w moves f6e6 f7e7 e6f6 e7f7
2bak4/4a4/4b4/9/6c2/6R2/4c4/4C4/4N4/3AKA3 b moves g5c5 g4c4 c5g5 c4g4
2cak4/4a4/9/2r6/9/9/9/2N1BC3/4A4/2BAK4 w moves c2d4 c6c4 d4c2 c4c6
The most practical(and least disputed) rule book of the day:
