What does the ending of Princess Lanling mean?

No one will die. Princess Lanling's ending should be the death of Zhou Guojun, the death of the warrior Lanling. Duanmu pitied Gao Changgong's mother to lead an ordinary life with a tragic ending. But in order to leave a happy ending, the soldier Lan Ling was dug up by the general and survived again. He went to visit Jiegu with Duanmu and said that Yu Wenyong had run away with a crazy woman and a young woman. Generally speaking, he didn't want the audience to argue, so he left a suspense to make the audience want to go! It feels a bit like the anime of the heroine in Riman, such as Amnesia, which is such an ending without saying who the heroine is with, leaving only suspense.
