I started watching late..
Whose baby was it? Ma's or Luo's? Who was in the lake with her?
shareIt was Luo's baby and Luo and her made love in the lake. But there are also scenes, when all 3 are at the lake together.
If you liked the ending, it is a really beautiful movie - I would watch it, you missed so much. If you are in the US, you can get it over Netflix, otherwise you can buy the DVD online...
