What do you mean, Guoyin sings men together?

The post horse "Sangmen" in China and India means that several ominous omens appear at the same time. The idiom "The country and India and postal services are the same as the mulberry door" indicates that disaster is coming. The "national seal" here refers to the national seal, which is stolen or lost; "Post Horse" refers to the official post horse hanging on the post station. If the post horse dies of illness, it means that there will be major changes in officials or higher-level institutions; "Sangmen" refers to the gate of the mourning hall, and a coffin passing through represents an ominous sign. This idiom is one of the ancient folk superstitions, and it is rarely used now.
