Liang Ping has Yin Yang Eyes and is the grandson of Fan Yuantang. If amnesia is related to ghosts, then it is more likely for Liang Ping to suffer from amnesia.
Hell's Movie indeed provided Liang Ping's life story to Qian Cangyi. However, it only contained some basic information. Besides, even Qian Cangyi himself cannot remember every single matter, so it's impossible to make a breakthrough from this aspect.
As for the manifestation of amnesia, Qian Cangyi suspects it's related to Liang Ping's condition last night.
From beginning to end, only one person met Granny Chen, and that person was Liang Ping, which is to say, Qian Cangyi.
Seeing is believing, but when playing alone, one needs to put a question mark at the end.
Suppose Liang Ping's Yin Yang Eyes are due to psychological issues and not actual Yin Yang Eyes, Qian Cangyi would still see the Filthy Object.
This can be somewhat corroborated in "The Lost Kingdom".
