Is the next Qianlong dress an adapted version of Princess Huanzhu?

I'm not sure what the phrase 'next wear Qianlong' means because I don't know the meaning of this phrase. However,"Princess Huanzhu" was a famous online novel that told the story of Little Swallow and Crape Myrtle. As far as I know, this story is often adapted into movies, TV series, animations and other forms. Some people think that some of its plots are different from the original. However, whether or not " The Next Emperor Qianlong " was an adapted version of " Princess Huanzhu " required more specific information.
