How to solve the Chinese chess endgame?

As soon as the car enters three, it looks like five and returns to seven.

If the car is flat, it will be 3, and the taxi will be 5, 6.

Car six into one, five into 1,

Car 3 draws 4 (four rounds here, red wins, but there are still a few steps behind)

Four into five.

Seven into five, five into two.

Handsome, 5 draws and 4 draws, so far no solution.
