Red to play and draw.

This puzzle is entitled "Chun Bu Zang Yue", we give it the translation of "Within Limits". It is from the book "The Complete Game of Xiangqi".

We will give the solution in a few days' time, however a hint to facilitate solving of the puzzle is that all moves were played with the limits (of the three middle files), what an amazing Xiangqi composition indeed.
