逢着天门 Does anyone know the meaning of this saying or idiom? It is part of the commentary to a Shenshu verse, which doesn't really make sense to me, but it seems this expression more or less explains the verse.
The full sentence goes like this:"去到长安，东北转角，逢着天门，便有下落", comes from Zhuge Shenshu Verse No.355. If you feel it doesn't make sense, then you get the point. This book was used to do Fortune-telling, so it meant to confuse the readers, so the Fortune-tellers can pick up from here, use their knowledge (verbal tricks) to explain your destiny. A word to word translation: "Go to Chang An (The Capital City), north east corner, Meet Tianmen (Can be explained into a certain place or a certain time), then you find it."
