简介：Normally at this time of year, Purple Mountain would be closed off, allowing only those with status in Leizhou City to enjoy the scenery. Ordinary people were not allowed to enter. Since the second prince came to Leizhou, this mountain has a purple cloud gathering on the top of the mountain every evening. He thought it was a sign of great auspiciousness, so he sent troops to block it, not allowing anyone to climb the mountain, and kept it to himself.
