2. The conclusion of the specific investigation process is not clearly stated. Presumably, it is because the modern prince already knows that hibiscus is dead, so ancient and modern correspond. Then zhina in ancient times, the prince was also a cruel woman. Furong would rather die than replace her sister, so her family must have hidden secrets;
In order to save the world, Furong guessed the puzzle and asked the prince to reward the persimmon poisoned by the prince. If Furong dies in the palace because of this, the prince must have something to do with it, then his family may be exposed by poisoning the prince. If they exchange clothes and pretend that the prince died by walking carelessly, then no one can question the prince's death at the same time. The ancient hibiscus flowers are pitiful. Save the one you love, but don't hurt the one you love. Love and affection can't be both. In the end, I can only choose suicide to save both sides!
