What does Druna mean at the Druna Hotel?

I feel that after the TV series is broadcast, netizens are open-minded, and even the name of the TV series has become a clue.

"Druna Hotel" mainly tells the story that the heroine Zhang Manyue became the owner of the Moon Hotel because of her evil deeds. Although she is a hotelier, she was imprisoned here for a long time to atone for her sins. The hero Ju Canxing was sold to Zhang Manyue by his father twenty years ago. Twenty years later, Ju Canxing became an excellent hotel manager, and he will soon take office in Moon Hotel. But Ju Canxing doesn't know that the guests received by Moon Hotel are actually ghosts wandering around the world, and Ju Canxing's past life has a deep entanglement with Zhang Manyue. ...

Druna Hotel is an inn with a history of thousands of years. In modern times, it has become a hotel. The woman claimed that the full moon lived for 1000 years. The hotel is full of photos of her in different periods, and her style has changed a lot.

The full moon, which committed a great crime and was tied to the old tree to stop the flow of life and death, is like a tree without leaves and flowers. The full moon only "exists" in De Luna Hotel 1000 years, which proves that her long years are photo frames decorated on a wall of the full moon room.

From the late Korean period, from the Beijing era, and from the second half of 1900 to the present, there are photos of Druna and the full moon. Not only can you learn about the invisible full moon life through radio, but you can also see the different names and appearances of Druna in different times from the Moon Inn to the Full Moon Hall.

Wedding killings, firefly stalks, blown gauze towels representing the past between the hero and heroine, teaching the heroine to write Chinese names, etc. These highly similar plots are blended together, and it's really hard to believe that Druna Hotel didn't learn from East Palace.
