What do you mean how many lonely people are in the world of mortals?

How lonely the world of mortals is, is that the world of mortals is very lonely. All we have is the present time, and all we can walk or walk is this life. Loneliness is a ghost lurking in the depths of the soul. All kinds of enjoyment and stimulation of silk and bamboo are disgusting to the mouth, extremely flashy to the eyes and extremely tired to the ears, which can greatly please the senses, but it will also produce the ability to think independently.

The stimulation of the world of mortals, it is difficult to cross the physical barrier, at best, can only temporarily soothe the soul. Lonely ghosts, however, like to empty people's hearts after a night of fighting flute and hangover.
