Lion : piece moving on the Queen's lines with the help of a sautoir and being able to go beyond with for limit, either an obstacle or the edge of the chessboard
Very aesthetic
it becomes more complicated with the third problem which is one of the first production with Chinese pieces

Shrinking Men : a piece can only make one move of a length inferior or equal to its previous move
The Black King not being in check, the Queen's last move could only be inferior to 3
Kings having changed colour, they can only make one horizontal or vertical move, but not diagonal
Very instructive and simple, but destabilizing !
Of course, the symmetrical position does not have the same solution at all!
