Did the male protagonist in the movie 77 Days really die in the end?

I don’t know whether he is dead or not, but Yang Liusong, the prototype of the story, survived, otherwise we would not know such a story. The ending of the movie is an open ending, allowing us to expand our endless imagination. Putting aside the real story, as far as the plot of the movie itself is concerned, the male protagonist encounters an accident and lives in the arms of Qiangtang forever, or the male protagonist finally overcomes the difficulties and returns to the female protagonist. With the Lord, everything is possible.
