Fast answer
March is a facing puzzle. Crossing is a straight-line build puzzle.
The march puzzle asks you to manage enemy facing, tile coverage, and morale. The crossing puzzle asks you to build a short, straight path. Treat both as rule checks first and route guides second.
Player question
Why does Hutuo March fail?
The main failure is walking into a tile where two enemies face you at once. Back out, change the angle, then continue when only one enemy is front-locking you.

What are the win conditions?
You need both conditions: defeat every enemy and step through every map tile. Clearing only the enemies is not enough.

What is the efficient March route idea?
Circle around the outside first, then cut inward. That covers tiles cleanly and reduces wasted turns or retreats.

How do I solve Hutuo Crossing?
Talk to Miaomiao, enter build mode, aim at the yellow marker, and place two or three supports on a straight start-to-finish line.
Jump to noteDo not force a double lock
In Hutuo March, the main danger is standing where two enemies face you at once. Retreat and reset the angle instead of pushing forward.
Win conditions are paired
The march puzzle needs both goals: clear every enemy and cover every tile. Missing either one can waste the run.
Circle before cutting in
The source recommends moving around the outside and then working inward to reduce wasted turns and cover the board cleanly.
Crossing supports should be straight
In Hutuo Crossing, place supports along the direct line from Miaomiao to the yellow marker and keep the gaps jumpable.
