森旅迷雾看不清谁嘴脸
[sēn lǚ mí wù kàn bù qīng shéi zuĭ liăn]
This can be interpreted as wandering through misty woods where one cannot distinguish faces. It illustrates situations where there is ambiguity in interpersonal relationships; difficulty identifying the real nature and intention of the people around you because of confusing surroundings or circumstances.
