Both opening books now run in the new translation: "The History Of A Family" and "An Unfortunate Gathering" — thirteen chapters, translated from the Russian original rather than from another translation.
The Chinese text of the game used to be Geng Jizhi's translation from the 1940s. It is in the public domain, which is why it could ship with the game at all. But its style is archaic by today's standards, and Chinese readers said so — some took the old text for machine translation. It is not machine translation. It is eighty years old.
Book II is where this showed most, because it takes place entirely inside a monastery.
The demo is exactly these first two books. So all of it now runs in the new translation: you can read it and judge it without buying anything.
It has not been deleted or overwritten. The settings carry a switch: the new translation, or Geng Jizhi, 1947. From Book III on the old translation continues either way, names included.
The developer is Russian and cannot judge for himself whether the new Chinese reads naturally or amounts to literature. If Chinese is your first language, read the first two books and say what they are worth. The thread for it: https://steamcommunity.com/app/4955990/discussions/0/590687864233187080/
