What is the ending of the novel "The Female Teacher in the Mountains"?

This is a senior novel. The ending I read was that Bai Jie followed Wang Shen back to his hometown, Gao Yi was still the principal and just chose other goals, and Sun Qian did not get divorced in the end, and the couple just went about their separate ways. Yes, it’s just that Sun Qian’s godfather passed away and Principal Gao had a happy ending. Even the mountains were planted with green trees and took on a new look.

Only Teacher Bai is still alone, he is the true love without boundaries and selfless dedication. Teacher Bai is the only teacher in the school. She is responsible for not only the education of the children in the school, but also the school affairs. In such a poor village, for children, studying is the only way out and the only hope. Teacher Bai knew this exactly, so he worked hard and devoted his life to staying on the front line of education. We must find a way out and hope for the future for the children in the mountains. In other words, he alone held up the hope of a village. A large number of young people go out to work, see the outside world, and understand the gap between themselves and the outside world, so that they can drive local economic development. Migrant work also requires a certain cultural foundation, and this cultural foundation is the contribution of Teacher Bai.
