A symbiosis between Xiangqi and Janggi with a few shogi aesthetics. You can open a .odg (OpenDocument Drawing) with Libre Office https://www.ecosia.org/search?q=Libre%20Office

1-As you can see I've simplified a few things in terms of notation. To simplify terminology, the Shogi system is used. Black is generally Sente and White is generally Gote, although this is not a hard and fast rule, and in Xjiangchess the Chess rules for colour are followed. Even the pawns have been Shogi-fied. To differentiate between the variants I make up and others I lean towards the term 'Chesswomen' for this and the others of my Chess Variants.

2-You can move up to two pawns side to side before crossing the river without any issues. You can move a third side-to-side before it crosses the river, but if you do and the opponent doesn't and the game ends in a draw on the board, your opponent will get 0.5+ (0.5/∞) board points while you will get 0.5- (0.5/∞). In other words, they'd have 1/∞ more than you and win the game.

3-The Fire Cannon moves as in Xiangqi while the Stone Cannon moves as in Janggi and they can start the game on the left or the right, but the second player to place pieces must maintain diagonal symmetry. Each piece has both characters, one on each side, in case players want to play only Xjiangqi or Janggi, or Xjiangchess, in which the canon flips after each move, or Xiangchess or Jangchess.

4-And this is the rule I'm most satisfied with. You can move up to one elephant across the river (or use the special Janggi move) and from then on that elephant would move like in Janggi, but not the second, which moves like in Xiangqi. Again there is a different symbol on the underside, in this case to flip to for when your elephant turns into a Janggi one.

5-Each general can start as in Xiangqi or Janggi. The Janggi rule for generals leading to a draw applies, and the Xiangqi rule for the Flying General manoeuvre also applies, but if you win this way, it's only by 0.5 a board point instead of 1 (you'll get 0.75 board points to the opponent's 0.25, instead of 1 to 0), so obviously in a winning position in a multi-game match one may choose not to use the Flying General.

6-Players place each piece alternately, and then this continued with the player placing the first piece also making the first actual game move. I think in Shogi and Chess, the lower-skilled player should always start first, or in a match of multiple games with the player having the first move alternating each match, the weaker player should play first in the first game. However in Xjianggqi the player who sets e ch piece up first is at a slight strategic disadvantage, and this is compensated by them also moving first. The ability to switch cannons for horses as in Xiangqi is there, however the ability to switch pieces as in Janggi are only allowed in multi-game matches, or in other words, the setup for the first game in any match should be the standard Xiangqi setup. From the fourth game on, any setup along the first row is allowed.

In Chessxjian, the queenside pieces replace Xjianggqi pieces on the Xjianggqi board, with Xjiangqi orientation maintained so black' queenside pices are diaogonal to white's. And Xjianchess is when Xjianggqi pieces replace the queenside pieces on a chess board with them facing each other directly with chess orientation, each canon having replaced a pawn too, with similar rules applying for Chesshogi/Shochess, and Xjianshogi/Shoxjianggqi. In Chessxjian and Xjianchess, the canons can start the game on either side, but they flip after each move. In Chessxian, Xianchess, Chessjang, Jangchess, there's of course no need for flipping canons.

I would like to note that it's clear Go influenced the Chess games of China and Korea, and Japan. The Chinese copied the physical, tangible aspect of putting the pieces on lines instead of quadrilaterals, which matches with their genophenic and cultural leaning. On the other hand, the Japanese incorporated the aspect of prisoner stones from the territory scoring rules they got from china before china switched back to area scoring, and this is a combination of the Japanese genophenic and cultural leaning to look at the internal philosophy of a thing, and also the fact that in their samurai culture they were already hypersensitive to the concept of prisoners and being a prisoner due to traditions of honour and uses as a form of diplomacy surrounding it being much more formalised (than in the west before the modern period, let's say)
