The emoji combination "👨🏼🦯➡️" usually represents directional content related to guiding the blind. For example, it may indicate the direction of a passageway exclusive for the blind, or the directional indication for guiding the blind to move forward.
When I saw a 👨🏼🦯➡️ sign ahead, I knew it was a special passage.
On this map, this 👨🏼🦯➡️ icon is very conspicuous.
