I can't give a definite answer as to whether writing novels in China Sky is reliable or not because I don't have enough information to evaluate the reliability of this situation. However, writing a novel was a personal creative activity, as long as one abided by local laws and regulations and was careful not to violate the rights of others. Of course, in order to protect their own rights, it was best to keep some supporting documents such as writing outlines, manuscripts, etc. in case of emergency. There was no need for an ID card to write a novel because an ID card was not included in the creation. However, when it comes to copyright and other issues, you need to keep the relevant identification documents for legal proceedings.
