Legend of Zhen Huan, Palace Lock Heart Jade, and Palace Lock Pearl Curtain were the three classics of time travel dramas. They not only had fascinating plots but also had a huge fan base. Many people would have a strong interest in time travel dramas after watching these dramas. In my opinion, although these three time-travel dramas have unique plot settings and character images, they still have some flaws in the plot and character creation. Some of the plots were too brainless or did not conform to historical facts, making the audience feel a little awkward. Some of the characters 'personalities and behaviors were too exaggerated, making the audience feel uncomfortable. However, time-travel dramas were still one of the most popular forms of entertainment. Many people liked to experience different cultures and historical backgrounds by watching time-travel dramas. For those who liked time-travel dramas, these three classic time-travel dramas were still a good choice.
