Which experience is better to read the original novel first or the adapted film and television works first?

The movie Alive is based on the novel Alive by Yu Hua and Reed. The original novel is solid and full. I think there are two places in the film adaptation that go beyond the original. It is meaningful to use shadow play props before and after the movie. In the movie, Long Er, who won Fu Gui Yard by gambling, was written as a master of shadow play. When he lost the gambling, Fu Gui borrowed money from him, and Long Er lent the props of the shadow play to Fu Gui to make his own money. Fu Gui carried this box of shadow play all over the street, and was finally caught by the Kuomintang army. Fu Gui first played a shadow play for the national army down archers, then was captured by the army of the * * * production party, and then played a shadow play for the * * * military exercise. After liberation, he played a shadow play for the workers in steelmaking; In the 1960s, his shadow play props were finally "closed for maintenance" and destroyed by fire. This is not in the novel. In the novel, Fu Gui's daughter Xia Feng bled to death while giving birth to a child. When the film was adapted, a rebellious young doctor was added to turn the old professor into a reactionary academic authority. In order to ensure the birth of the child, the son-in-law Wan brought an old professor from the cowshed. They made some steamed buns for the old professor to eat first. Who knows, the old professor ate seven steamed buns and drank several glasses of water, but his stomach burst. Finally, there was a massive hemorrhage in Xia Feng, and the young doctor was helpless, and the old professor died, which caused a great tragedy on the earth. This is more profound than the novel.
