Magic and wonder could be a theme. Just like in Western stories about Tinkerbell, in Chinese novels, there might be elements of magic that the Tinkerbell - like characters possess.
Harmony with nature is also likely to be a theme. Chinese culture has a strong connection with nature. So in these 'tinkerbell Chinese novels', the Tinkerbell - like characters may be in tune with the natural world, perhaps using natural elements to perform magic, and also teaching humans or other beings the importance of respecting and living in harmony with nature.
One possible theme could be motherhood. It could explore how Tinkerbell adjusts to the idea of becoming a mother, her fears, and her hopes. Another theme might be family, as it could involve the support she gets from her fairy friends or any family she might have in the fairy world. Also, growth could be a theme, as she grows both personally and in her relationships during this new stage of life.
One possible plotline could be that Tinkerbell's pregnancy is a magical accident. Maybe she was exposed to some strange magic that caused this unexpected situation. Another could be that she is in love with a fairy or a character from the Peter Pan universe and they are starting a family together.
I'm not very familiar with specific 'tinkerbell Chinese novels'. But you could try searching on Chinese literature platforms or in libraries, where you might find some novels related to fairies like Tinkerbell with Chinese elements.
Maybe it's about loyalty. Tinkerbell has been by Peter's side for a long time. She might see Peter as not just a friend but also as a symbol of Neverland. So, if there's a threat to Peter that could potentially destroy Neverland as well, she would sacrifice herself to ensure his survival and the safety of their world.
Maybe she sacrifices herself to save Peter Pan from a great danger, like a powerful enemy in Neverland.
Some common themes in a dark Tinkerbell fanfiction could be jealousy. For example, Tinkerbell might be jealous of another fairy's relationship with Peter Pan. Another theme could be power struggles. Maybe Tinkerbell is trying to gain more power in Pixie Hollow. Also, there could be themes of betrayal, like if a friend betrays Tinkerbell for their own gain.
For Tinkerbell, she might become more open - minded. Since Vidia has a different personality, Tinkerbell could learn to accept different ways of thinking. For Vidia, she could become less aloof. The kiss could be a turning point where she starts to engage more with the other fairies. For example, she might start joining group activities instead of always being on her own.
Another theme could be adaptation. Maybe the story is about how the Chinese adapt to the idea of having a turkey for Christmas, or how the concept of Christmas is adjusted in a Chinese - influenced setting related to the turkey.
If the 'Remarry no way' Chinese novel exists, one possible theme could be the idea of self - independence. The protagonist may choose not to remarry to show that they can be self - sufficient without relying on a new marriage. Another theme might be loyalty, either to a former spouse or to a certain set of values.
One possible theme could be the passage of time and how it changes people. As the years go by, characters may experience different levels of 'intoxication' in the form of love, ambition, or the pursuit of knowledge. Another theme might be the search for identity during those 'intoxicating' years. People often try to figure out who they are when they are caught up in various intense experiences.
