The reason why palace dramas after Legend of Zhen Huan were easy to become classics was mainly because of the following reasons: 1. The production level is uneven: the production level of palace drama varies from company to company. Some companies focus on the plot and character creation to create high-quality works, while others focus more on traffic and commercial value. They may ignore the production quality for short-term profits. 2. The subject matter is too sensitive: The subject matter of palace dramas usually involves women's rights, marriage, family, power and other topics. These topics still have strong controversy and differences in modern society, so it is difficult to gain widespread recognition and acceptance. 3. Different audiences have different preferences: different audiences have different preferences for palace dramas. Some viewers may prefer suspense, history, secret agents, and other types of TV dramas rather than overly complicated palace dramas. 4. Limited word-of-mouth communication: Due to the younger audience of palace dramas, the effect of word-of-mouth communication may not be as good as other types of TV dramas. Moreover, some palace dramas had flaws in the plot and character creation, making it difficult for them to win the audience's recognition and praise. Therefore, if a palace drama wanted to become a classic, it needed to make a better balance and choice in terms of production quality, theme selection, audience preferences, and so on. At the same time, it needed to pay attention to word-of-mouth communication and self-reflection in order to gain more recognition and classic status.
