dead too realistic

Dear leaders: Hello, I am a newcomer to the underworld. I am new to the underworld. There is one thing I don't know. Please give me an explanation.Although this ghost died unexpectedly, but currently he has no obsessions in his heart, and he does not want to take revenge. May I ask why he is still forcibly detained in the yang world and cannot go to reincarnation for further studies?Sincerely, I salute Chu Shuangbai on the mid-July and half of Bingshen’s Hungry Ghost Festival. He held high the 1V1 banner.
