I learned that Rao Xueman's Hourglass is a very popular novel. It has been published as a physical book and many e-books and has a large number of readers on the Internet. Although there is no official news about it being made into a movie or TV series, the plot and characters of the novel are very attractive, so there may be a film or TV adaptation. However, we still need to wait for the official announcement to determine if such a situation will happen.
