What is the ending of the movie The Nightingale?

1, the mayor is not a good person, but he cares about his daughter (the kidnapper asked for so much ocean, so he gave it without thinking), and her daughter worshipped Yan Dahai as a hero because she saved his life. The end is likely to be secretly helping Yan Dahai escape (if Yan Dahai is not dead) (and this is my wild guess)

2. One position of the fish tank was photographed several times, and other positions were cracked several times, giving several close-ups.

3. In the end, only two people who knew Zhou Qian were alive, 1 Yan Dahai and 1 Zhou, but when Zhou died, Yan Dahai was relieved and his life and death were uncertain.

Ya Ya saw that the kerosene lamp on the table was full of diamonds, and immediately ran out to find someone, indicating that Yan Dahai should still be alive. After all, .................................................................................................................................... is looking for ghosts? No one can know the secret of diamonds, let alone the mayor. I see, there will be no diamonds in the end.

Finally, Ya Ya said that Yan Dahai ate steamed buns, and then she released a boat with clay figurines on it. The channel below flows out. I don't know where it went. This movie doesn't explain, but it can't be for the dead, can it?

These are my thoughts ... of course, on the surface, the ending of the movie means that Yan Dahai is dead ... but this movie is an ending without specific statement, that is to say, you can think whatever you want. It is an open ending, leaving you with a suspense guess.
