What are the three provinces of cockcrow?

I am surprised to see your question. First of all, we need to understand the meaning of rooster crow and three provinces. This means that if a rooster crows in the morning, it can be heard in three provinces. This is what the ancients called the golden rooster crowing in unison, which is known to all three provinces. But which province do the three provinces refer to specifically? It is Guizhou Province, Sichuan Province and Yunnan Province respectively. Hope the answer helps you.
