Thanks @AndyAnderson for your help. I get the result by using Calculate adjacent field tool.

Use the tool Generate Near Table:

https://pro.arcgis.com/en/pro-app/2.8/tool-reference/analysis/generate-near-table.htm

The default behavior should include all adjacent or overlapping polygons, and if you include the parameter argument angle = 'ANGLE', the table will include an angle which you can use to determine direction.

If there are gaps, however, you won’t be able to use the default option Closest but should set the parameter argument search_radius to be somewhat greater than zero.

That’s cool, wouldn’t expect to find that in the Cartography tool box. One caveat, though, it doesn’t appear that it will find every adjacent polygon, and a given polygon might be listed more than once.
