On the train, Holly and Xiaoya are holding Zhao Li's piano.
Holly told the children across the street that the piano was dumb and could not make a sound, but later he used Xiaoya to pour water. He was able to dial out the piano that once belonged to Zhao Li and make a sound, which showed that Zhao Li did not die.
When the imperial sacrifice of Mount Tai wanted to take away a soul, it should have taken away Holly's human-god, but Zhao Li survived.
Extended data
First, Xia Dongqing (the protagonist of "Ghost Ferry")
When she was a child, Holly's parents and sister both died in a car accident, and he was the only survivor. Memory began in the orphanage, and it seems that it began at that time.
He found himself with a pair of eyes that can see ghosts. Because of this unusual ability, Holly was ostracized since she was a child, with a withdrawn personality and no friends.
Until he came to convenience store No.444, where he first faced his abilities and ghosts haunting in the dark, gave them help and found his own value; He has friends, Zhao Li, Mulan and Wang. Of course, he may be an enemy. ...
Second, Zhao Li.
He said he was a thousand years old. According to the dialogue in the first season of Five Sons, the last meeting between Five Sons and Zhao Li was in Wumanghua, which can be traced back to the Western Jin Dynasty. In fact, Zhao Li's age is likely to reach 2000.
Zhao Li's true identity is unknown. His present position is the ferryman of convenience store 444. Convenience store 444 is actually a dead man's post. Zhao Li's job is to extradite these dead people from the underworld to the underworld and embark on their journey.
But for a thousand years, for such a long time, Zhao Li was a monk in his previous life before he became a ferryman. Unable to become a Buddha because of a female ghost, he exchanged souls and memories with Aga, the hades, and became a soul ferryman.
